Subject: [PATCH 2/3] Implement confirm on close for unsaved buffers

- Modify close_request to send :q command to neovim instead of closing immediately
- Let neovim handle unsaved changes confirmation with its standard behavior
- Preserve existing vimleavepre -> io_loop -> close() flow for clean exit
- Prevent accidental data loss from Alt+F4 or window close button
