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
+
+## v2.0.5 (2026-05-23)
+
+### Fixed
+- **Critical**: Translation proxy now uses system Node.js instead of Electron binary
+  - Previous: Electron's `process.execPath` would start a GUI process instead of CLI Node
+  - Now: Auto-detects system Node via `which node` fallback to `/usr/bin/node`
+- **Critical**: Removed duplicate proxy start (was running proxy twice, causing port conflicts)
+  - `main.js` no longer starts `apiProxy` — `ensureProxyStarted()` in `languageServer.js` handles it
+- **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
+
+### Changed
+- Proxy stdout/stderr now piped to parent for proper logging
+- `syncProviderToEndpoints()` runs on every startup (not just first run)
+- Version bumped to 2.0.5
+
+### Verified E2E Flow
+- ✅ First-run welcome screen appears correctly
+- ✅ Provider selection (Google Gemini / Custom) works
+- ✅ Settings window opens and saves correctly
+- ✅ Provider config synced to `~/.codex/endpoints.json` on every startup
+- ✅ Translation proxy starts on port 48080 with correct backend config
+- ✅ Language Server spawned with `--api_server_url http://127.0.0.1:48080`
+- ✅ Proxy health/models/endpoints endpoints all respond correctly
+- ✅ `--ag-reset` flag correctly re-triggers welcome screen
+- ✅ Proxy survives LS restarts and port changes

-# AG X (Antigravity fork) v2.0.3
+# AG X — Antigravity Fork
 
-AI-Powered Code Intelligence — agentic desktop application with multi-provider AI support.
+**AG X** is a fork of the Antigravity desktop application with enhanced multi-provider support. It allows you to use Google OAuth or any custom OpenAI-compatible API provider.
 
-## What's New in v2.0.3
+![AG X Icon](icon.png)
-
-### 🐛 Critical Fix: Provider Selection Flow
-- **Welcome screen now shows BEFORE the Language Server starts** — on first run, the user picks a provider before the LS launches, preventing the Google OAuth prompt from appearing for non-Google providers.
-- **Provider config syncs to `~/.codex/endpoints.json`** — the provider choice from the welcome screen and settings panel is properly synced to the endpoints config that the translation proxy reads.
-- **"Another AI Provider" flow fixed** — when user picks a custom provider, the settings panel opens and the app waits for the user to configure and save their provider before starting the Language Server.
-
-### Changes
-| File | Change |
-|---|---|
-| `main.js` | Restructured startup: welcome screen before LS start |
-| `main.js` | Added `syncProviderToEndpoints()` function |
-| `main.js` | Google Gemini handler sets active endpoint in `endpoints.json` |
-| `main.js` | Custom provider handler waits for settings save before continuing |
-| `providerSettings.js` | Save handler syncs to `endpoints.json` and emits `provider:settings-saved` |
-| `providerSettings.js` | Added close-settings IPC listener |
-| `settings.html` | Save handler shows restart notification and auto-closes |

-## Installation
+- 🔄 **Multi-Provider Support** — Switch between Google OAuth and custom API providers
+- ⚡ **Custom Endpoints** — Configure your own OpenAI-compatible API endpoints
+- 🌐 **Translation Proxy** — Built-in translation service proxy for multi-language support
+- 🔧 **Provider Settings UI** — Easy-to-use settings page for managing providers
+- 📦 **Debian Package** — Installable `.deb` package for Ubuntu/Debian
+- 🖥️ **System Tray** — Minimize to system tray with status indicators
+- 🔒 **Secure Storage** — Provider configurations stored locally and securely
+
+## Quick Start
+
+### Install from .deb
+
 ```bash
 sudo dpkg -i ag-x_2.0.3_amd64.deb
+sudo apt-get install -f  # fix any missing dependencies
 ```
 
-## First Run
+### First Run
-On first launch, AG X shows a welcome screen where you choose:
+
-1. **Google Gemini** — Sign in with Google (OAuth, no API key needed)
+1. Launch AG X from your application menu or run `ag-x`
-2. **Another AI Provider** — Pick from 15+ providers and enter your API key
+2. On first launch, you'll see the **Welcome Screen**
+3. Choose your provider:
+   - **Google OAuth** — Use the default Antigravity/Google authentication
+   - **Custom Provider** — Enter your own API endpoint URL and API key
+4. Start using the app!
+
+### Configure Provider
+
+After initial setup, you can change your provider at any time:
+- Click the AG X tray icon → **Settings**
+- Or use the in-app provider settings
