test: spell out AskUserQuestion everywhere instead of AUQ

Per user feedback: don't shorten AskUserQuestion to AUQ — the
abbreviation reads as cryptic. Apply across all the new code from this
branch:

- Rename test/skill-e2e-auq-format-compliance.test.ts →
  test/skill-e2e-ask-user-question-format-compliance.test.ts
- Touchfile entry auq-format-pty → ask-user-question-format-pty
  (touchfiles.ts + matching assertion in touchfiles.test.ts)
- Function rename navigateToModeAuq → navigateToModeAskUserQuestion
- Variable auqVisible → askUserQuestionVisible
- Outcome literal 'real_auq' → 'real_question'
- All comments + JSDoc + CHANGELOG entry write AskUserQuestion in full
- "AUQs" plural → "AskUserQuestions"

No behavior change. 49/49 free tests still pass.
