## What changed
- Retain question drafts, selections, expanded state, and handled message IDs across thread input restoration and reconnects. Preserve buffered live questions during session refresh without replaying their message text.
- Enable history recall and search in question answers, honoring updated key bindings and stripping image attachments and placeholders from recalled entries. Preserve Vim mode when an answer is not accepted.
- Let forward navigation past the last question restore the latest queued message as an editable main composer draft. Keep working status and queued messages visible alongside questions.
- Show a countdown for newly arrived collapsed questions and clear it when the question editor is opened or used.
- Disable question submission and skipping while the thread is unavailable.
## Testing
Add regression tests and snapshots for draft restoration and replay deduplication, history search and key bindings, queued-message editing, countdown rendering, and question layout with working status.
