* feat: allow multiline custom answers in clarification overlay
Swap the single-line custom-answer input for an auto-growing textarea so users
can type multi-line replies to ask_user_question. Enter submits, Shift+Enter
inserts a newline; the box grows to ~6 lines then scrolls. Adds unit and e2e
coverage.
* fix: address review feedback on multiline clarification input
- Always preventDefault on desktop plain Enter so an empty draft can't leak a
stray newline before the trim guard (Claude/CodeRabbit).
- On coarse-pointer devices let Enter insert a newline and submit via the
existing Submit button; hide the keyboard hints on touch (mobile parity).
- Preserve newlines in the resolved clarification history message via
whitespace-pre-wrap + items-start.
- Strengthen e2e to guard against fused lines; add Ctrl+Enter and touch tests.
* fix: touch submit button and IME guard for clarification input
- Guard against submitting on the Enter that confirms an IME candidate
(e.nativeEvent.isComposing) on CJK keyboards.
- Add an inline Send button on coarse-pointer devices so single-question custom
answers (which have no overlay Submit button) have a touch-reachable send
path. Fixes the regression from switching touch Enter to newline.
* refactor: extract clarification custom-input controls
- Pull the Enter/⇧↵ hints and touch Send button into a CustomInputControls
subcomponent to shrink ClarificationCustomInput.
- Compute the trimmed draft once and reuse it across the keydown handler and the
Send button (disabled state, click, styling) so the conditions can't drift.
- Add a test asserting the touch Send button is disabled while isSubmitting.
* fix: ignore auto-repeat Enter in clarification custom input
A held Enter key emits auto-repeat keydown events; guard the handler with
e.repeat so it can't fire onSubmit more than once. Adds a regression test.
* fix: suppress newline on repeat Enter and add mobile clarification e2e
- Repeat Enter on desktop now calls preventDefault before bailing, so a held key
can't leak newlines into the current or next question's textarea after the
carousel advances; it still never re-fires onSubmit/finalize.
- Add a mobile-chrome (Pixel 5) e2e covering the touch path: Enter inserts a
newline and the inline Send button submits the multiline answer.
* test: consolidate clarification e2e seed helper
Extract the shared seed → navigate → waitForLoad flow into
e2e/helpers/clarification.ts and delegate from the clarification, resize, and
mobile specs instead of duplicating it in each.
