agent terminal: multi-line textarea input

Browse source 
swap the single-line <input> for an auto-growing <textarea>. enter
submits, shift+enter newlines, ime composition respected (skip submit
while isComposing). height caps at ~12em then scrolls. submit-hint
updates to '↵ send · ⇧↵ newline'. async-form handler now also clears
textareas on success.
