RIAutomobility: Unofficial Port

Narrow fresh-key update for Minecraft 26.1.2: new seat-switch defaults use H, avoiding Minecraft Quick Actions on G and Momentum cruise resume on R. The action ID and registration are unchanged; no forced rebinding or options migration was added. Existing saved/custom mappings are not rewritten by this update; choose H manually in Controls if desired. Production assets and licenses are unchanged. Per-target unit and exact-binary/source checks passed. Three native H runs were explicitly waived for this narrow update: native H/remap, controller and player acceptance remain NOT PROVEN. This is not a broader Automobility/Momentum gameplay qualification.
