Addresses two Minor follow-ups from the Task 4 code review:
- findFilenameInput previously included `body` in its closest() selector,
meaning any "auto" textarea outside a modal would walk all the way up
and pick up the files-editor modal's filename input from elsewhere in
the document. Drop `body` so out-of-modal "auto" usage degrades
cleanly to "plain".
- setValue now dispatches an `input` event on the textarea after
writing, matching the onUpdate mirror. Task 10 wires the files-editor
modal to call setValue when loading file content — without this fix,
textarea-listening code (e.g. unsaved-changes indicators) wouldn't
see programmatic loads. Now setValue and user typing produce the
same observable side effects.
Plan source block updated to match.
