Update x64 client with base room rendering fixes

Ship REM-Client c36a43e1f2d99bc7ddfb968e75272f4e71ade01c.
Clear ray tracing instances and temporal history between base rooms, and
add independent room GI quality with a one-ray Low default and SSAO fallback.

Release x64 builds, GI budget checks, Freeport 9 room transitions and
REM menu saving were validated. Runtime/data hashes match the Lutris
installation across 11,143 files; original SAVE files remain unchanged.
Preserve the five upstream story arc commits already on this branch.
