Fixes the synthetic car_select jump for cold sessions, makes the loadout
exit chain safe for real (non-synthetic) events, and adds a native->Kotlin
GameEvents bridge (onMapLoaded/onRaceStarted/onRaceEnded/onUpgradesAccepted/
onCarSelected) so both the UI layer and a future native RatNet client can
learn what the player picked - car id, accepted upgrades, and paint color
(name + RGBA) are all resolved live from the game's own engine state
rather than a static extracted table, so they stay correct for any car
added later. Includes a Jetpack Compose overlay as a worked example of a
UI-side GameEventListener consumer.
Full investigation history, root causes, and the several dead ends ruled
out along the way are documented in PROGRESS.md (cont. 30-63b).
