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.

 ## Validation expectations
 - Backend changes: run `npm run test:server` when possible.
 - Frontend changes: run `npm run test:client` when possible.
+- Full suites take 5–6 minutes, so while iterating run only what the change touches: `npm run test:server -- server/__tests__/<name>.test.js`, and in `client/` `NODE_ENV=test npx vitest related <changed files> --run` (or `vitest run <test file>`). Run the full suite once before committing, and always when the change touches something every screen uses (`Layout`, `Sidebar`, `StatusBar`, `tailwind.config.js`, global CSS, shared hooks/lib) — the per-screen snapshots catch that.
 - If any check is skipped, report it explicitly.
