feat: implement spec synchronization feature for improved project management

- Added a new `/sync` endpoint to synchronize the project specification with the current codebase and feature state.
- Introduced `syncSpec` function to handle the synchronization logic, updating technology stack, implemented features, and roadmap phases.
- Enhanced the running state management to track synchronization tasks alongside existing generation tasks.
- Updated UI components to support synchronization actions, including loading indicators and status updates.
- Improved logging and error handling for better visibility during sync operations.

These changes enhance project management capabilities by ensuring that the specification remains up-to-date with the latest code and feature developments.
