Refactor Auto Mode Service and add feature verification and project analysis capabilities

- Refactored AutoModeService to delegate tasks to specialized services: featureLoader, featureExecutor, featureVerifier, contextManager, and projectAnalyzer.
- Implemented feature verification logic in a new FeatureVerifier service, which runs tests and updates feature status.
- Added ProjectAnalyzer service to scan project structure and update app_spec.txt.
- Removed obsolete methods related to feature loading and context management from AutoModeService.
- Updated feature status handling to ensure context files are deleted when features are verified.

This refactor enhances modularity and maintainability of the codebase, allowing for better separation of concerns in feature management.
