v0.3.12-rc7

This pre-release corrects restart-time map provenance and map-transition recovery. A restored map, room overlay, pose, history, and floor-bound controls remain unavailable until fresh independent live map layers agree. Expired one-sided transition evidence now triggers bounded revalidation and retries safely; stale asynchronous map work cannot replace newer verified state.

Install through HACS with beta versions enabled, restart Home Assistant, and verify real two-map behavior. Do not share private maps, room names, identifiers, addresses, or credentials in feedback.

Final v0.3.12 remains held until real two-map acceptance succeeds on this exact commit.
