## Why
Async questions with suggested choices only accepted those choices. Allow users to write an alternative answer directly in the question pane.
## What changed
- Append an editable Other choice. Typing or pasting opens it, while number shortcuts still submit named choices.
- Preserve custom drafts when switching choices, reject blank Other submissions, and distinguish the input from a suggested choice named Other.
- Support Vim editing and search in question inputs while keeping arrow keys available for choice navigation.
- Wrap custom answers inline, cap the editor height, and keep the input visible in narrow layouts.
## Testing
Add interaction tests and snapshots covering custom answer delivery, draft preservation, selector key repeats, blank answers, remapped shortcuts, Vim editing and search, and narrow or wrapped layouts.

## Why
Asynchronous questions can include suggested answers, but the TUI previously displayed only a freeform input. Show those choices and require them to be fully visible before submission.
## What changed
- Render numbered, wrapped choices with a default selection, list navigation, and digit shortcuts. Submit the selected label as the answer.
- Block submission of clipped choices and prompt the user to expand the terminal. Limit option processing to the first 32 entries and discard labels over 512 bytes.
- Preserve freeform input when no usable choices remain, and add contextual submit, skip, and question navigation hints.
- Ignore repeated submit keys so holding a key cannot answer another question.
## Testing
Add state, snapshot, and chat widget tests covering wrapped and clipped choices, constrained layouts, option limits, long answer preservation, oversized answer rejection, key repeats, and conflicting keybindings.

## What changed
- Introduce an async-question editor component with per-question drafts, navigation, replay deduplication, and submit or queue handling using the shared composer.
- Add bounded `AnsweredQuestion` framing that truncates question text at a UTF-8 boundary and flattens line breaks before prepending it to an answer.
- Add `prompt_stack_back` and `skip_question` keybinding actions and the `tui.question_esc_back` setting. Normalize `Ctrl+]` and `Ctrl+5` for key matching and conflict detection, and let default question shortcuts yield to explicit bindings.
- Flush buffered typing in both the main composer and the covering view so background input cannot keep the draw loop waiting.
The async-question component is not yet connected to the TUI event flow.
## Testing
Add regression coverage for bounded Unicode question framing, question-shortcut conflicts, and paste-buffer flushing in background and covering editors.
