The "+" attach control called fileInputRef.current.click() programmatically.
When the textarea is focused with text, clicking "+" blurs it first and the
browser drops the programmatic picker-open (user-activation gating), so no file
could be attached while typing. Replace it with a real <label> wrapping the
file input — native label activation always opens the picker, regardless of
focus/text state.
