feat: add resume interrupted features endpoint and handler

- Introduced a new endpoint `/resume-interrupted` to handle resuming features that were interrupted during server restarts.
- Implemented the `createResumeInterruptedHandler` to check for and resume interrupted features based on the project path.
- Enhanced the `AutoModeService` to track and manage the execution state of features, ensuring they can be resumed correctly.
- Updated relevant types and prompts to include the new 'ux-reviewer' enhancement mode for better user experience handling.
- Added new templates for UX review and other enhancement modes to improve task descriptions from a user experience perspective.
