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
