A one-shot grok container whose entrypoint ran grok_auth --check and found
the token missing/expired exits 78 (EX_CONFIG). Crash-retrying 3x burns
tokens for zero progress — the agent cannot start without a valid token.
Park the provider with kind=auth_missing (same shape as the 429 exit-75
path) so the probe-resume loop revives the task once grok_auth.refresh_if_stale
mints a fresh token; if still expired, the next exit 78 re-parks (no burn).
Also fixes a latent F035 regression: _park_provider_unavailable now registers
a WaitingRecord, so the bare-__new__ rate-limit park test had to set
_waiting_records + stub _persist_waiting_record (mirrors the overload-test
fixture).
