Handoff records: durable writer/reader for locator rendezvous.

A HandoffWriter publishes locators with monotonically increasing FenceEpoch generations to block storage. A HandoffReader polls the same block storage and detects when a new generation has been written.

The underlying persistence uses the same checkpoint shape as grafos-collections durable snapshots: a header block followed by postcard-serialized data blocks.

§Fail-closed

Corrupt or unreadable records cause the reader to return an error, never a stale or default value.
