+ Optional client-provided idempotency key for safe request retries.
+
+ When present, the server ensures no additional effects for requests
that carry the same
+ Idempotency-Key within the same operation/resource scope. If a prior
request with this key
+ has been finalized, the server returns the previously finalized
response instead of
+ re-executing the mutation.
+
+ Finalization rules:
+ - Finalize & replay: 200, 201, 204, and deterministic terminal 4xx
+ - Do not finalize (not stored/replayed): 5xx, 409 request_in_progress
+
+ Key Requirements:
+ - Key format: UUID (V7 preferred)
