Crypto ETF Sentinel — Launch-timing tracker for ``launch_imminent`` US spot crypto ETF issuers: days-waiting + percentile vs the historical 8-A12B → CERT/EFFECT distribution. Returns the historical baseline in ``meta`` on every call, so the response is useful even when the current cohort is empty. Indicative timing data, not a predicted launch date.

We sent a real GET request to this endpoint and it answered 402 with payment requirements we could parse.
