Replaces the key material. The previous value stops working immediately; the new value is returned once.
Rotation is not naturally idempotent: every call mints a new key and kills the previous one. When retrying over an unreliable network, always send an Idempotency-Key — a blind retry would invalidate the key you just received.

Optional but recommended. Retrying with the same value replays the first result — it does not mint a second key.
