Plugins:

• Completion via nvim-cmp + Copilot
• Telescope for fuzzy finding
• Neo-tree file explorer
• Harpoon for quick file navigation
• DAP for debugging
• Git integration (lazygit)
• Glance for LSP peek definitions/references
• Search and replace with Spectre
• Code folding with nvim-ufo
• Session management
• Which-key for keybinding discovery
• Mini.nvim utilities
• Catppuccin colorscheme + Lualine statusline
