Mirror of the kithmoot change: a kind 20468 epoch request now carries `admission`, an HMAC under HKDF(epoch-0 room key, "kithmoot/v1/epoch-request-key") over roomId:authority:device:created_at. The creator's recovery responder refuses a request without one before the policy is consulted, so a stranger who reads a room id and its authority off a public rekey event is never answered. The body keeps v:1, so a responder from before this ignores the field and a web desk from after it refuses a client from before it. The vendored vectors file gains only the new epochRequestAdmission group (5 vectors, run by EpochRequestAdmissionVectorsTest); the rosterEvent call-* vectors the web file has since gained are not brought across here.
