Problem: The 'autoread' option only checks for file changes reactively — on FocusGained, :checktime, CmdlineEnter, etc. — by polling timestamps. External changes are not detected until the user interacts with Neovim. Solution: Add a core module (runtime/lua/nvim/autoread.lua) enabled from runtime/plugin/autoread.lua that watches each buffer's file using vim._watch.watch() (libuv fs_event). On change detection it calls :checktime, which invokes the existing buf_check_timestamp() logic for reload/prompt handling. Watchers are managed via autocmds tied to buffer lifecycle events and respect the 'autoread' option (global and buffer-local).
