Consume commonlib's delivery lifecycle, classify finite replication entry points, and document why the five-minute inactivity fuse is only a leak safety valve. Record the remote-activity counter correction and preserve continuous replication's unbounded live channel.
Reason:
- A client that remains open during a remote database rebuild can retain the previous Security Seed and upload documents encrypted with the wrong key.
Changes:
- Fetch the remote Security Seed at every replication preflight instead of reusing the process cache.
- Add a regression test and an unreleased change note for issue #1018.
