fix(streaming): stop replaying committed recenter retirements

Browse source 
Root cause: pending-only live projection buckets were misclassified as landblock presentation owners during origin recentering. That manufactured a second full cleanup receipt for a generation whose first receipt was still advancing; the duplicate guard threw and the broad retry path replayed the already-committed detach 243 times.

Keep pending live projections through the spatial identity map without issuing another receipt, and fail fast when a receipt-ledger invariant occurs after detachment. Evidence: docs/research/2026-08-02-collision-throughput-handoff/p1-retirement-receipt-loop.md. Release suite, lifecycle gate, and nine-stop soak pass.
