Add v2.0.5 .deb package

Critical fixes:
- Translation proxy now uses system Node.js (not Electron binary)
- Removed duplicate proxy start causing port conflicts
- Added port availability check before spawning proxy
- Fixed welcome:choice double resolve()
- Fixed settings.html close using deprecated remote
- Fixed translationProxy /v1 for openai-compat backends
- Proxy no longer detached/unref - properly tracked as child
- SingletonLock cleanup on startup

Verified E2E:
- Welcome screen on first run ✓
- Provider selection works ✓
- Settings save + sync ✓
- Translation proxy starts correctly ✓
- LS connects to proxy ✓
- --ag-reset works ✓

 # AG X Changelog
 
-## v2.0.3 (2025-05-22)
+## v2.0.5 (2026-05-23)
 
-### Features
+### Fixed
-- **Multi-Provider Support**: Choose between Google OAuth or Custom Provider at first launch
+- **Critical**: Translation proxy now uses system Node.js instead of Electron binary
-- **Provider Settings UI**: Built-in settings page to configure custom API endpoints
+  - Previous: Electron's `process.execPath` would start a GUI process instead of CLI Node
-- **API Proxy**: Transparent proxy that routes requests to your chosen provider
+  - Now: Auto-detects system Node via `which node` fallback to `/usr/bin/node`
-- **Translation Proxy**: Supports translation services for multi-language responses
+- **Critical**: Removed duplicate proxy start (was running proxy twice, causing port conflicts)
-- **Welcome Screen**: First-run experience lets you select your preferred provider
+  - `main.js` no longer starts `apiProxy` — `ensureProxyStarted()` in `languageServer.js` handles it
-- **System Tray Integration**: Minimize to tray with status indicators
+- **Critical**: Added port 48080 availability check before spawning proxy
+  - Prevents duplicate proxy processes from leftover/orphaned instances
+- **Fixed**: Welcome screen `welcome:choice` handler had double `resolve()` call
+  - Added `return` after Google Gemini handler to prevent fallthrough
+- **Fixed**: `settings.html` close button used deprecated `remote.getCurrentWindow()`
+  - Now uses `ipcRenderer.send('provider:close-settings')` exclusively
+- **Fixed**: `translationProxy.applyConfig()` now appends `/v1` for `openai-compat` backends
+- **Fixed**: Proxy process is no longer `detached:true` with `unref()` — properly tracked as child
+- **Fixed**: SingletonLock cleanup on startup to prevent stale lock issues
 
-### Fixes
+### Changed
-- Fixed provider selection flow - selecting a custom provider now correctly opens the app
+- Proxy stdout/stderr now piped to parent for proper logging
-- Fixed endpoint configuration sync between AG X UI and Language Server proxy
+- `syncProviderToEndpoints()` runs on every startup (not just first run)
-- Fixed OAuth redirect handling for custom providers
+- Version bumped to 2.0.5
-- Fixed settings persistence across app restarts
 
-### Architecture
+### Verified E2E Flow
-- `dist/main.js` - Electron main process with provider orchestration
+- ✅ First-run welcome screen appears correctly
-- `dist/languageServer.js` - Language Server proxy with endpoint management
+- ✅ Provider selection (Google Gemini / Custom) works
-- `dist/provider/welcome.html` - First-run provider selection screen
+- ✅ Settings window opens and saves correctly
-- `dist/provider/settings.html` - Provider configuration settings page
+- ✅ Provider config synced to `~/.codex/endpoints.json` on every startup
-- `dist/providerSettings.js` - Provider settings window management
+- ✅ Translation proxy starts on port 48080 with correct backend config
-- `dist/services/apiProxy.js` - API request proxy to custom endpoints
+- ✅ Language Server spawned with `--api_server_url http://127.0.0.1:48080`
-- `dist/services/providerService.js` - Provider CRUD operations
+- ✅ Proxy health/models/endpoints endpoints all respond correctly
-- `dist/services/translationProxy.js` - Translation service proxy
+- ✅ `--ag-reset` flag correctly re-triggers welcome screen
+- ✅ Proxy survives LS restarts and port changes
