✨ feat: Implement Resumable Generation Jobs with SSE Support

- Introduced GenerationJobManager to handle resumable LLM generation jobs independently of HTTP connections.
- Added support for subscribing to ongoing generation jobs via SSE, allowing clients to reconnect and receive updates without losing progress.
- Enhanced existing agent controllers and routes to integrate resumable functionality, including job creation, completion, and error handling.
- Updated client-side hooks to manage adaptive SSE streams, switching between standard and resumable modes based on user settings.
- Added UI components and settings for enabling/disabling resumable streams, improving user experience during unstable connections.
