feat(neovim): migrate to nixvim with minimal plugins (#260)

Replace bare programs.neovim with programs.nixvim. Only 3 plugins: neo-tree (file explorer), catppuccin (colorscheme), treesitter. Add core editor opts matching helix defaults: clipboard, cursorline, scrolloff, wrap, mouse, undofile, smart search, split direction. Enable 5 LSP servers: nixd, rust-analyzer, gopls, pyright, bashls. Signed-off-by: Ryan Yin <xiaoyin_c@qq.com>
