Migrate from home-manager neovim to NixVim
Major configuration migration following 2025 best practices: - Add nixvim flake input with proper nixpkgs following - Import nixvim.homeManagerModules.nixvim in home configuration - Convert nvim.nix from programs.neovim to programs.nixvim - Migrate all settings to declarative NixVim syntax: * vim.opt.* → opts.* * vim.g.mapleader → globals.mapleader * Raw Lua keymaps → structured keymaps array * Plugin configs → declarative plugin options - Preserve all functionality: * Gruvbox hard contrast colorscheme * nvim-tree with dotfile/gitignore filters * Treesitter with all grammars * Lualine with relative paths and gruvbox theme * Fugitive git integration * System clipboard keybindings * All leader key mappings Benefits: Type safety, better documentation, cleaner code structure 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
