test(migration): establish W2 native oracle and release removed overlay identities

Add the sequential W2/completion plan and deterministic earthquake ground-raster, geometry, lifecycle and strict runtime QA. Prove the comparator rejects incomplete evidence and release deleted overlay entries from the collision arbiter. Record native dev/preview acceptance and full checkpoint gates.
