feat(cursor): Enhance context injection and project registry management

- Updated `context-inject.sh` to refresh context before prompt submission and ensure worker is running.
- Added functionality to register and unregister projects for automatic context updates in `worker-service.ts`.
- Implemented methods to read and write the cursor project registry, allowing for better management of installed hooks.
- Integrated context updates into the `GeminiAgent`, `OpenRouterAgent`, and `SDKAgent` to ensure the latest context is available during sessions.

This update improves the integration of Claude-Mem with Cursor, ensuring that context is consistently updated and accessible across sessions.
