fix: v2.7.5 — the chat shows each AskUserQuestion with the user's answer

- Chat: an AskUserQuestion is its own card (AskCard in MessageList.tsx), not
  part of the collapsed work line — each question with the option picked or
  the text typed, "declined" when refused. The transcript route passes the
  answers from Claude Code's toolUseResult (askAnswers, beside diff).
- Chat: the activity panel keeps the user's open/close per session for the
  tab, and opens by default only once the session has an output.
- Workspace home: the sent prompt's draft is dropped even though opening the
  session unmounts the home.
- Terminal: Ctrl+V with text on the clipboard pastes the text; only an empty
  clipboard still sends ^V.
- AGENTS.md / CLAUDE.md: run only the tests a change touches while iterating,
  the full suite once before committing.
