Enhance blog features and improve backend functionality

- Added a VS Code-style editor with YAML frontmatter support and live preview.
- Implemented force reparse functionality for immediate updates of posts.
- Improved directory scanning with error handling and automatic directory creation.
- Introduced new CLI commands for cache management: `reinterpret-all` and `reparse-post`.
- Enhanced logging for better debugging and monitoring of the Rust backend.
- Updated README to reflect new features and improvements.
