feat: Enhance Command Palette with Fuzzy Search and Improved UI

Browse Source 
- Implemented fuzzy search functionality for command filtering, allowing for more flexible command matching.
- Updated Command Palette UI to include a scoring system for commands based on usage and recency.
- Added new command categories and improved display organization with a table format.
- Introduced recent and frequent command tracking for better user experience.
- Refactored command handling to support dynamic command execution and improved navigation.
