Critical fixes:
- ALWAYS sync active AG X provider to endpoints.json on startup
(previously only synced on first run, causing LS to use stale data)
- Add --no-sandbox to proxy process spawns (fixes SIGTRAP crash on Linux)
- Add --no-sandbox for all Electron modes (not just headless)
- Add --ag-reset flag to re-trigger welcome screen
- Bump version to 2.0.4
Root causes fixed:
1. endpoints.json was never updated after first-run, so LS used wrong provider
2. Electron child processes (translation proxy) crashed due to SUID sandbox
3. No way to re-show provider selection after initial setup
Features:
- Welcome screen on first run (provider choice before LS starts)
- 15+ AI providers (Google Gemini, OpenAI, Anthropic, DeepSeek, Ollama, etc.)
- Provider config syncs to endpoints.json for translation proxy
- Built-in Node.js translation proxy for non-native backends
- Auto-update support, tray integration, URI scheme handler
