Document the phased migration from MacVim + Vundle + Vimscript to Neovim with its native conventions and ecosystem. The plan is split into 7 phases ordered by dependency so each phase can land independently and leave a working editor: 1. Minimum cutover (also closes #64) 2. Remove Vim-only quirks 3. Replace Vundle with lazy.nvim (foundational for 4-7) 4. Replace syntastic with built-in LSP + nvim-lint 5. File navigation and search (telescope, oil/nvim-tree, ripgrep) 6. Treesitter and completion (nvim-cmp) 7. Convert init.vim to init.lua Each phase is tracked in its own GitHub issue (#67-#73).
Phase 1 of the Neovim migration: stop launching MacVim, start launching Neovim, with the smallest reasonable diff. Modernizing the plugin manager, linter stack, search, and Lua conversion are deferred to later phases (#68-#73). The previous setup ran `mvim -v` against `~/.vimrc` with ~30 Vundle plugins. Most carry over unchanged; the exceptions are called out below. Changes: - Move `home/.vimrc` to `home/.config/nvim/init.vim` and prepend the Neovim → Vim runtimepath shim so Vundle continues finding `~/.vim/bundle/`. - Drop the explicit `undodir` block — Neovim's default `~/.local/state/nvim/undo//` is already outside the homesick castle and auto-created (closes #64). - Drop `set pastetoggle=<F2>` — option removed in Neovim 0.10 (bracketed-paste handles this automatically). - Drop `ervandew/supertab` plugin — incompatible with Neovim 0.12's Lua-callback default mappings; tab completion will be restored via nvim-cmp in Phase 6 (#72). - Drop `flazz/vim-colorschemes` plugin — abandoned 6 years ago with no explicit Neovim support. Switch the active colorscheme from `railscasts` (a community port from that collection) to `new-railscasts` from the already-installed `carakan/new-railscasts-theme` plugin, which is actively maintained and has dedicated markdown / error-state styling. Enable `termguicolors` since the new colorscheme is gui-defined. - Switch `vim` alias to `nvim` in `home/.zshrc`. - Switch bootstrap to `nvim +PluginInstall +qall` in `init.zsh`. - Remove `brew 'macvim'` from `Brewfile`. - Update `README.md` to describe the transitional Neovim + Vundle state and link to `PLAN.md`. Closes #64. Implements #67.

Summary
Phased migration from MacVim + Vundle + Vimscript to Neovim with its native conventions and ecosystem. This draft PR will accumulate Phase 1 commits; later phases may be split into separate PRs.
The phases are designed so each one can land independently and leave a working editor:
