chore(explore): add 260727 canonical-beacon backfill migration master

Backfill the three known production aliases in cap and vouch facts, then rebuild canonical aggregate counts from those facts while preserving the latest recorded activity. Delete the colliding alias rows only after recounting. Real-SQLite coverage pins the production-shaped result, idempotent reruns, and full rollback on an intermediate failure.
