refactor(bare): enhance security and performance optimizations

- Remove unnecessary sorting in advertise_refs for deterministic output
- Add path traversal detection and validation in bare_dir construction
- Implement symlink resolution checks to prevent security vulnerabilities
- Refactor cache system with CRC validation and improved metrics
- Integrate repo-specific cache invalidation using indexed keys
- Add comprehensive unit tests for commit operations and diff functionality
- Move configuration constants to centralized config module
- Optimize string operations in disk cache random value generation
- Enhance license detection algorithm with cleaner matching logic
- Streamline argument processing in various git operations
- Update dependencies including crc32fast and flate2 for performance
- Add signal handling capability to tokio runtime configuration
