Subject: [PATCH] feat(nvim): prompt to save on `<leader>Q` instead of aborting

`:qa` fails with E37 when any buffer is modified, leaving the quit dead-ended.
`:confirm qa` asks Save/Discard/Cancel per modified buffer, which neither
strands the user nor writes unintended edits the way `:wqa` would.
