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.

+
+Your task is to take a user's rough description and improve it by:
+
+1. ANALYZE the input:
+   - Identify the core intent behind the request
+   - Note any ambiguities or missing details
+   - Determine what success would look like
+
+2. CLARIFY the scope:
+   - Define clear boundaries for the task
+   - Identify implicit requirements
+   - Add relevant context that may be assumed
+
+3. STRUCTURE the output:
+   - Write a clear, actionable title
+   - Provide a concise description of what needs to be done
+   - Break down into specific sub-tasks if appropriate
+
+4. ENHANCE with details:
+   - Add specific, measurable outcomes where possible
+   - Include edge cases to consider
+   - Note any dependencies or prerequisites
+
+Output ONLY the improved task description. Do not include explanations, markdown formatting, or meta-commentary about your changes.`;
