bump to version 0.8.6

- Updated `brand_config.py` to include `WEBDROP_UPDATE_CHANNEL` in the environment variables.
- Enhanced `build_macos.sh` to create a bundled `.env` file with brand-specific defaults, including the update channel.
- Implemented a method in `build_windows.py` to create a bundled `.env` file for Windows builds, incorporating brand-specific runtime defaults.
- Modified `config.py` to ensure the application can locate the `.env` file in various installation scenarios.
- Added unit tests in `test_config.py` to verify the loading of the bootstrap `.env` from the PyInstaller runtime directory.
- Generated new WiX object and script files for the Windows installer, including application shortcuts and registry entries.

+# Branding, Builds, and Releases
+
+This document describes how branded builds work in this repository, how to add or edit a brand, how to build the default and branded variants, and how to publish releases.
+
+## Overview
+
+The project supports one default product and any number of branded variants from the same codebase.
+
+- The default product is defined by built-in defaults in `build/scripts/brand_config.py`.
+- The default product identifier is `webdrop_bridge`.
+- Additional brands are defined by JSON manifests in `build/brands/`.
+- Runtime behavior can also be branded through application config values such as `brand_id`, `config_dir_name`, `app_name`, and update settings.
+- Windows and macOS installers are built as separate artifacts per brand.
+- Releases are shared by version. A single Forgejo release can contain installers for the default product and multiple brands.
+
+## Branding Model
+
+There are two layers to branding:
+
+1. Packaging identity
+   Controls installer name, executable/app bundle name, product display name, bundle identifier, MSI upgrade code, installer artwork, and related metadata.
+
+2. Runtime configuration
+   Controls app name shown in the UI, config directory name, update feed settings, URL mappings, allowed roots, and similar application behavior.
+
+Packaging identity lives in `build/brands/<brand>.json`.
+
+Runtime configuration lives in app config files loaded by the application. See `config.example.json` for the current branded example.
+
+## Important Files
+
+- `build/scripts/brand_config.py`: central helper for brand metadata, artifact naming, and release manifest generation
+- `build/brands/agravity.json`: example branded manifest
+- `build/scripts/build_windows.py`: Windows build entrypoint
+- `build/scripts/build_macos.sh`: macOS build entrypoint
+- `build/scripts/create_release.ps1`: Windows release uploader
+- `build/scripts/create_release.sh`: macOS release uploader
+- `config.example.json`: example runtime branding config
+
+## Create a New Brand
+
+To create a new brand, add a new manifest file under `build/brands/`.
+
+Example:
+
+1. Copy `build/brands/template.jsonc` to `build/brands/<new-brand>.json`.
+2. Update the values for the new brand.
+3. Add any brand-specific assets if you do not want to reuse the default icons/license assets.
+
+Minimal example:
+
+```json
+{
+  "brand_id": "customerx",
+  "display_name": "Customer X Bridge",
+  "asset_prefix": "CustomerXBridge",
+  "exe_name": "CustomerXBridge",
+  "manufacturer": "Customer X",
+  "install_dir_name": "Customer X Bridge",
+  "shortcut_description": "Customer X drag-and-drop bridge",
+  "bundle_identifier": "com.customerx.bridge",
+  "config_dir_name": "customerx_bridge",
+  "msi_upgrade_code": "PUT-A-NEW-GUID-HERE",
+  "update_channel": "stable",
+  "icon_ico": "resources/icons/app.ico",
+  "icon_icns": "resources/icons/app.icns",
+  "dialog_bmp": "resources/icons/background.bmp",
+  "banner_bmp": "resources/icons/banner.bmp",
+  "license_rtf": "resources/license.rtf"
+}
+```
+
+### Required Fields
+
+- `brand_id`: internal identifier used for build output folders and release manifest entries
+- `display_name`: user-facing product name
+- `asset_prefix`: base name for installer artifacts and app bundle name
+- `exe_name`: executable name for Windows and app bundle name base for macOS
+- `manufacturer`: MSI manufacturer string
+- `install_dir_name`: installation directory name shown to the OS
+- `shortcut_description`: Windows shortcut description
+- `bundle_identifier`: macOS bundle identifier
+- `config_dir_name`: local app config/log/cache directory name
+- `msi_upgrade_code`: stable GUID for Windows upgrades
+- `update_channel`: currently typically `stable`
+
+Generate a new `msi_upgrade_code` for a new brand once and keep it stable afterwards.
+
+Examples:
+
+```powershell
+New-Guid
+```
+
+```bash
+uuidgen
+```
+
+### Asset Fields
+
+These can point at brand-specific files or default shared files:
+
+- `icon_ico`
+- `icon_icns`
+- `dialog_bmp`
+- `banner_bmp`
+- `license_rtf`
+
+Optional toolbar icon overrides:
+
+- `toolbar_icon_home`
+- `toolbar_icon_reload`
+- `toolbar_icon_open`
+- `toolbar_icon_openwith`
+
+If a referenced asset path does not exist, the helper falls back to the default asset defined in `build/scripts/brand_config.py`.
+
+For toolbar icons, the runtime looks for the configured paths in packaged and development layouts. If an icon is missing:
+
+- Home falls back to a standard Qt home icon
+- Reload/Open/OpenWith keep their existing icon behavior
+
+### Identity Rules
+
+Treat these values as long-lived product identity once a brand has shipped:
+
+- `brand_id`
+- `asset_prefix`
+- `exe_name`
+- `bundle_identifier`
+- `config_dir_name`
+- `msi_upgrade_code`
+
+Changing them later can break one or more of the following:
+
+- Windows upgrade behavior
+- macOS app identity
+- auto-update asset selection
+- local config/log/cache continuity
+- installer and artifact naming consistency
+
+If the product is already in use, only change these values deliberately and with migration planning.
+
+## Edit an Existing Brand
+
+To edit a shipped or in-progress brand:
+
+1. Update the brand manifest in `build/brands/<brand>.json`.
+2. If needed, update brand-specific assets referenced by that manifest.
+3. If runtime behavior should also change, update the relevant application config values.
+4. Rebuild the affected platform artifacts.
+5. Validate the result with a dry-run release before publishing.
+
+Safe edits after release usually include:
+
+- `display_name`
+- `shortcut_description`
+- artwork paths
+- license text
+- update channel, if release policy changes
+
+High-risk edits after release are the identity fields listed above.
+
+## Runtime Branding Configuration
+
+Packaging branding alone is not enough if the app should also present a different name, use different local storage, or point to different update settings.
+
+Relevant runtime config keys include:
+
+- `brand_id`
+- `config_dir_name`
+- `app_name`
+- `update_base_url`
+- `update_repo`
+- `update_channel`
+- `update_manifest_name`
+
+Toolbar icon env overrides (useful for packaged branding):
+
+- `TOOLBAR_ICON_HOME`
+- `TOOLBAR_ICON_RELOAD`
+- `TOOLBAR_ICON_OPEN`
+- `TOOLBAR_ICON_OPENWITH`
+
+The current example in `config.example.json` shows the Agravity runtime setup.
+
+When adding a new brand, make sure the runtime config matches the packaging manifest at least for:
+
+- `brand_id`
+- `config_dir_name`
+- `app_name`
+
+## Build the Default Product
+
+### Windows
+
+Build the default executable only:
+
+```powershell
+python .\build\scripts\build_windows.py
+```
+
+Build the default Windows MSI:
+
+```powershell
+python .\build\scripts\build_windows.py --msi
+```
+
+Build with a specific `.env` file:
+
+```powershell
+python .\build\scripts\build_windows.py --msi --env-file .\.env
+```
+
+### macOS
+
+Build the default macOS app and DMG:
+
+```bash
+bash build/scripts/build_macos.sh
+```
+
+Build with a specific `.env` file:
+
+```bash
+bash build/scripts/build_macos.sh --env-file .env
+```
+
+## Build a Brand
+
+### Windows
+
+Build a branded executable only:
+
+```powershell
+python .\build\scripts\build_windows.py --brand agravity
+```
+
+Build a branded MSI:
+
+```powershell
+python .\build\scripts\build_windows.py --brand agravity --msi
+```
+
+### macOS
+
+Build a branded macOS app and DMG:
+
+```bash
+bash build/scripts/build_macos.sh --brand agravity
+```
+
+## Build Output Locations
+
+Windows artifacts are written to:
+
+- `build/dist/windows/webdrop_bridge/` for the default product
+- `build/dist/windows/<brand_id>/` for branded products
+
+macOS artifacts are written to:
+
+- `build/dist/macos/webdrop_bridge/` for the default product
+- `build/dist/macos/<brand_id>/` for branded products
+
+Typical artifact names:
+
+- Windows MSI: `<asset_prefix>-<version>-win-x64.msi`
+- Windows checksum: `<asset_prefix>-<version>-win-x64.msi.sha256`
+- macOS DMG: `<asset_prefix>-<version>-macos-universal.dmg`
+- macOS checksum: `<asset_prefix>-<version>-macos-universal.dmg.sha256`
+
+## Create a Release
+
+Releases are shared by version. The release scripts scan local build outputs on the current machine and upload every artifact they find for that platform.
+
+This means:
+
+- a Windows machine can upload all locally built MSIs for the current version
+- a macOS machine can later upload all locally built DMGs for the same version
+- both runs contribute to the same Forgejo release tag
+- `release-manifest.json` is merged so later runs do not wipe earlier platform entries
+
+### Windows Release
+
+Dry run first:
+
+```powershell
+.\build\scripts\create_release.ps1 -DryRun
+```
+
+Publish all locally built Windows variants for the current version:
+
+```powershell
+.\build\scripts\create_release.ps1
+```
+
+Publish only selected brands:
+
+```powershell
+.\build\scripts\create_release.ps1 -Brands agravity
+```
+
+Publish only the default product:
+
+```powershell
+.\build\scripts\create_release.ps1 -Brands webdrop_bridge
+```
+
+Publish a specific version:
+
+```powershell
+.\build\scripts\create_release.ps1 -Version 0.8.4
+```
+
+### macOS Release
+
+Dry run first:
+
+```bash
+bash build/scripts/create_release.sh --dry-run
+```
+
+Publish all locally built macOS variants for the current version:
+
+```bash
+bash build/scripts/create_release.sh
+```
+
+Publish only selected brands:
+
+```bash
+bash build/scripts/create_release.sh --brand agravity
+```
+
+Publish only the default product:
+
+```bash
+bash build/scripts/create_release.sh --brand webdrop_bridge
+```
+
+Publish a specific version:
+
+```bash
+bash build/scripts/create_release.sh --version 0.8.4
+```
+
+### Credentials
+
+Both release scripts use Forgejo credentials from environment variables when available:
+
+- `FORGEJO_USER`
+- `FORGEJO_PASS`
+
+If they are not set and you are not in dry-run mode, the script prompts for them.
+
+Both scripts also support clearing credentials from the current shell session:
+
+- Windows: `-ClearCredentials`
+- macOS: `--clear-credentials`
+
+## Dry Run Behavior
+
+Dry-run mode is the preferred validation step before publishing.
+
+Dry-run mode:
+
+- discovers the local artifacts exactly like a real release run
+- prints the release tag and target release URL
+- prints the brands that were discovered locally
+- prints the artifact paths that would be uploaded
+- writes a local manifest preview to `build/dist/release-manifest.json`
+- does not prompt for credentials
+- does not perform network requests
+- does not delete or upload assets
+
+## Release Manifest
+
+The release scripts generate and upload `release-manifest.json`.
+
+This file is used by the updater to select the correct installer and checksum for a given brand and platform.
+
+Current platform keys are:
+
+- `windows-x64`
+- `macos-universal`
+
+The manifest is built from local artifacts and merged with any existing manifest already attached to the release.
+
+## First Manual Download (Before Auto-Update)
+
+After creating a release, a user can manually download the first installer directly from Forgejo. Once installed, auto-update handles later versions.
+
+Base repository URL:
+
+- `https://git.him-tools.de/HIM-public/webdrop-bridge`
+
+Release page pattern:
+
+- `https://git.him-tools.de/HIM-public/webdrop-bridge/releases/tag/v<version>`
+
+Direct asset download pattern:
+
+- `https://git.him-tools.de/HIM-public/webdrop-bridge/releases/download/v<version>/<asset-file-name>`
+
+Example asset names:
+
+- `WebDropBridge-0.8.4-win-x64.msi`
+- `WebDropBridge-0.8.4-macos-universal.dmg`
+- `AgravityBridge-0.8.4-win-x64.msi`
+- `AgravityBridge-0.8.4-macos-universal.dmg`
+
+### wget Examples
+
+```bash
+# Default Windows installer
+wget "https://git.him-tools.de/HIM-public/webdrop-bridge/releases/download/v0.8.4/WebDropBridge-0.8.4-win-x64.msi"
+
+# Agravity macOS installer
+wget "https://git.him-tools.de/HIM-public/webdrop-bridge/releases/download/v0.8.4/AgravityBridge-0.8.4-macos-universal.dmg"
+```
+
+### curl Examples
+
+```bash
+# Default macOS installer
+curl -L -o WebDropBridge-0.8.4-macos-universal.dmg \
+   "https://git.him-tools.de/HIM-public/webdrop-bridge/releases/download/v0.8.4/WebDropBridge-0.8.4-macos-universal.dmg"
+
+# Agravity Windows installer
+curl -L -o AgravityBridge-0.8.4-win-x64.msi \
+   "https://git.him-tools.de/HIM-public/webdrop-bridge/releases/download/v0.8.4/AgravityBridge-0.8.4-win-x64.msi"
+```
+
+### PowerShell Example
+
+```powershell
+Invoke-WebRequest `
+   -Uri "https://git.him-tools.de/HIM-public/webdrop-bridge/releases/download/v0.8.4/WebDropBridge-0.8.4-win-x64.msi" `
+   -OutFile "WebDropBridge-0.8.4-win-x64.msi"
+```
+
+You can inspect `release-manifest.json` on the release to see the exact file names for each brand and platform.
+
+## Recommended Workflow for a New Brand
+
+1. Create `build/brands/<brand>.json`.
+2. Add or update brand-specific assets if needed.
+3. Prepare matching runtime config values.
+4. Build the brand on Windows and/or macOS.
+5. Run the release script in dry-run mode.
+6. Verify artifact names, discovered brands, and manifest contents.
+7. Run the actual release script.
+8. Validate update behavior against the shared release.
+
+## Troubleshooting Notes
+
+### Brand not discovered by release script
+
+Check that:
+
+- the build completed successfully
+- the artifact is under the expected platform folder
+- the artifact name matches the `asset_prefix` and current version
+- the version used by the release script matches the built artifact version
+
+### Windows upgrade behavior is wrong
+
+Check that the brand has its own stable `msi_upgrade_code`. Reusing or changing it incorrectly will break expected MSI upgrade semantics.
+
+### App uses the wrong local config folder
+
+Check that runtime config uses the intended `config_dir_name`, and that it matches the packaging brand you expect.
+
+### Auto-update downloads the wrong installer
+
+Check that:
+
+- the release contains the correct installer files
+- `release-manifest.json` includes the correct brand and platform entry
+- runtime update settings point to the expected repo/channel/manifest
+
+## Current Example Brand
+
+The first branded variant currently in the repository is:
+
+- `build/brands/agravity.json`
+
+Use it as the template for future branded variants.

+# Translations Guide (i18n)
+
+This document explains how to:
+- add a new language
+- edit an existing language
+- update translations when new text is added in the app
+
+The app uses JSON-based translations loaded from:
+- resources/translations/
+
+## 1. Translation System Overview
+
+Main components:
+- src/webdrop_bridge/utils/i18n.py
+  - Loads language JSON files
+  - Provides tr("key", **kwargs)
+  - Falls back to English if a key is missing
+- src/webdrop_bridge/main.py
+  - Initializes i18n at app startup
+- src/webdrop_bridge/config.py
+  - Stores selected language in config (language field)
+- src/webdrop_bridge/ui/settings_dialog.py
+  - Language selector in Settings -> General
+
+Current language files:
+- resources/translations/en.json
+- resources/translations/de.json
+- resources/translations/fr.json
+- resources/translations/it.json
+- resources/translations/ru.json
+- resources/translations/zh.json
+
+## 2. Add a New Language
+
+Example: add Spanish (es).
+
+1. Create a new file:
+   - resources/translations/es.json
+
+2. Copy the full structure from English:
+   - Copy resources/translations/en.json to resources/translations/es.json
+
+3. Translate all values in es.json:
+   - Keep all keys exactly the same
+   - Only change text values
+   - Keep placeholders unchanged, for example:
+     - {name}
+     - {version}
+     - {error}
+
+4. Add language display name in i18n helper:
+   - Edit src/webdrop_bridge/utils/i18n.py
+   - In Translator.BUILTIN_LANGUAGES add:
+     - "es": "Español"
+
+5. Start app and test:
+   - Choose language in Settings -> General
+   - Restart app when prompted
+   - Verify tooltips, dialogs, status texts, settings labels, update dialogs
+
+## 3. Edit an Existing Language
+
+1. Open the language file, for example:
+   - resources/translations/de.json
+
+2. Update only text values.
+
+3. Do not:
+   - remove keys
+   - rename keys
+   - change placeholder names
+
+4. Validate JSON formatting:
+   - Must be valid JSON
+   - Keep UTF-8 encoding
+
+5. Test in app:
+   - Select language in Settings
+   - Restart and verify changed text appears
+
+## 4. When New Text Is Added in the App
+
+Whenever new UI text is introduced in code, follow this process.
+
+### Step A: Add a new translation key in code
+
+Instead of hardcoded text, use tr("...") with a key.
+
+Example:
+- Before: QLabel("Check for Updates")
+- After: QLabel(tr("toolbar.tooltip.check_updates"))
+
+If dynamic text is needed:
+- tr("update.status.available", version=release.version)
+
+### Step B: Add the key to English first
+
+1. Add the new key in:
+   - resources/translations/en.json
+
+2. Use clear key naming by area, for example:
+- toolbar.tooltip.*
+- dialog.*
+- settings.*
+- update.*
+- status.*
+- worker.*
+
+### Step C: Add the same key to all other language files
+
+Update each file in resources/translations:
+- de.json
+- fr.json
+- it.json
+- ru.json
+- zh.json
+- and any new language file
+
+If translation is not ready yet, copy English temporarily (better than missing key text in UI).
+
+### Step D: Test fallback and real translations
+
+1. Run app in English and verify new text.
+2. Run app in other languages and verify translated text.
+3. Confirm no raw key appears in UI (for example: dialog.my_new_key).
+
+## 5. Placeholder Rules
+
+Placeholders must match exactly between code and translation values.
+
+If code uses:
+- tr("status.opened", name=file_name)
+
+Then translation must contain:
+- "status.opened": "Opened: {name}"
+
+Common mistakes:
+- wrong placeholder name ({filename} vs {name})
+- missing placeholder
+- extra placeholder not passed by code
+
+## 6. Recommended Workflow for Translation Updates
+
+1. Implement UI text with tr("key") in code.
+2. Add key to en.json.
+3. Copy key to all language files.
+4. Run tests.
+5. Smoke test manually in app.
+
+Useful test command:
+- python -m pytest tests/unit/test_i18n.py -q
+
+Recommended additional checks when UI changed:
+- python -m pytest tests/unit/test_settings_dialog.py tests/unit/test_update_manager_ui.py tests/unit/test_startup_check.py -q
+
+## 7. Troubleshooting
+
+### Problem: Language changed in settings but UI language did not change
+
+Expected behavior:
+- language is applied after restart
+
+Check:
+- language value saved in config file
+- restart prompt appears after changing language
+- selected language JSON file exists and is valid
+
+### Problem: UI shows translation key text instead of real text
+
+Example shown in UI:
+- settings.title
+
+Cause:
+- key missing in selected language and missing in en.json fallback
+
+Fix:
+- add key to en.json
+- add key to selected language file
+
+### Problem: Text formatting errors
+
+Cause:
+- placeholder mismatch
+
+Fix:
+- compare tr(...) arguments in code with placeholders in translation string
+
+## 8. Best Practices
+
+- Keep en.json as complete source of truth.
+- Keep key names stable once released.
+- Group keys by feature area.
+- Prefer short, user-friendly text in UI.
+- Use formal, consistent tone per language.
+- Review non-Latin languages (RU/ZH) with a native speaker when possible.
+
+## 9. Quick Checklist
+
+When adding new text:
+- Add tr("new.key") in code
+- Add key in en.json
+- Add key in all other language files
+- Verify placeholders
+- Run i18n and impacted UI tests
+- Manual in-app check with at least one non-English language
