Initial commit: Codex Launcher — Any AI Provider

Multi-provider integration for OpenAI Codex CLI/Desktop.

- Translation proxy: Responses API ↔ Chat Completions / Anthropic Messages
- GTK launcher with endpoint management, provider presets, Desktop/CLI launch
- Codex Default mode (built-in OAuth, zero config)
- Browser UA injection for Cloudflare-protected providers
- Streaming SSE, tool calls, reasoning content support
- Profile backup/import, model auto-fetch, bulk import
- Zero pip dependencies (pure Python stdlib + GTK)
