fix: address PR review bot findings

cursor[bot] findings on #433:
- Nightly schedule no longer enables the paid opt-in suites: a schedule
  event has no diff base, so the change-detection fallback flagged every
  file-triggered suite, which would have billed the skill-behavior,
  accept-cleanup, and deepseek LLM suites nightly. The plan now pins the
  schedule event to deterministic suites plus the full live-e2e matrix,
  with a regression test.
- Dismissing the mount-error card no longer strands the session: while
  the bar is hidden in GENERATING the card is the only recovery surface,
  so dismiss now returns the state machine to PICKING (session and
  server truth survive for a later republish).
