feat: Major performance optimization and LSP stability improvements

- Add comprehensive file type filtering to prevent LSP errors on non-text files
- Fix image freezing issues during file searches in Telescope
- Optimize leader key response time (500ms → 200ms)
- Add performance monitoring tools and LSP health checks
- Implement safe file search commands to prevent crashes
- Add startup optimization and deferred heavy operations
- Enhance LSP error handling with timeouts and graceful fallbacks
- Optimize Treesitter, completion, and search performance
- Add comprehensive troubleshooting guide for LSP issues

Performance improvements:
- Faster scrolling and UI responsiveness
- Better memory management and startup times
- Reduced diagnostic updates and LSP overhead
- Automatic exclusion of problematic file types

New keymaps:
- <leader>pp - Performance monitoring
- <leader>pl - LSP health check
- <leader>pr - Restart LSP
- <leader>ff - Safe file search (prevents LSP errors)
- <leader>ft - Text files only search
