feat(s3/lifecycle): shard-aware meta-log reader

- ShardCount=16; ShardID(bucket,key)=top-4-bits of sha256(bucket||/||key)
- Reader subscribes via SubscribeMetadata starting at Cursor.MinTsNs(),
  filters events by shard, emits to caller-owned Events channel
- Cursor: per-(shard, ActionKey) position with monotonic Advance, Freeze
  for blocked actions, MinTsNs for subscription resume
- Persister interface with InMemoryPersister for tests; filer-backed
  impl lands with the worker integration
