 * Maps an idempotency-key hash back to the original user-provided key and scope.

 * The mapping is held for the lifetime of a single run: the worker clears it at
 * each run boundary (warm starts reuse the process), so it never accumulates
 * across runs. Within a run every registered key is retained regardless of how
 * many are created, so the key/scope metadata is never silently dropped.
