feat: Enhance Command Palette with Fuzzy Search and Improved UI
- 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.
