Organize and commit nvim configuration improvements

**Configuration Enhancements:**
- Enable Nerd Font support in init.lua
- Enhanced LSP configuration with better clangd setup
- Improved query driver paths and error handling
- Added support for more filetypes (cmake, tex, etc.)

**Plugin Management:**
- Add GitHub Copilot integration
- Remove experimental plugins (avante, completion, statusline, theme)
- Reorganize plugin imports for better structure

**Repository Maintenance:**
- Update .gitignore for better artifact handling
- Clean up unused plugin configurations
- Establish clean baseline for future development
