Optimize Neovim configuration structure and LSP setup

- Remove duplicate nvim-web-devicons loading (already in kickstart)
- Add clangd configuration to custom LSP setup with proper flags
- Replace complex clangd_helper with universal LSP reload keybind (<leader>lr)
- Clean up unused clangd target selection keybind
- Streamline plugin organization for better maintainability
