* vector: owner-prefixed lease tags; foreign leases get a long backstop
reap_expired exempted only process-local LIVE_TAGS — server B could
reap server A's live query lease at the 1h TTL. Tags now carry a
per-process instance id: own leases use the short TTL, foreign leases
only the 24h backstop, so a live query elsewhere keeps its pin while
dead-process tags still collect eventually.
* vector: pick the lease-tag format by segment count, not numeric-ness
An owner that is all decimal digits parsed as the legacy timestamp, so
its real timestamp was ignored and the lease never expired. The third
segment is what distinguishes {instance}-{ts}-{uuid} from {ts}-{uuid}.
