…up purge (DAK-6975)
BUG 1: sweep() only removed sessions from the in-memory Map — engine memories
persisted forever in RocksDB. Now tracks namespaces per session and calls
DELETE /v1/namespaces/{ns} on expiry (both sweep timer and resolve-time expiry).
BUG 6: Historical playground-demo-* namespaces accumulated from all past sessions.
Added startup purge that lists all namespaces and deletes playground-demo-* ones.
4 new tests: onExpire callback, resolve-time cleanup, trackNamespace dedup, no-op
when no namespaces tracked. All 64 tests pass.
