Distributed lock / idempotency primitive for multi-agent swarms

Distributed lock / idempotency primitive for multi-agent swarms. claim(key) returns a token if free (with TTL); release(token) frees it; check(key) reports whether held. Stops multiple agents from double-processing the same work item.
