- State_InGroup follow-recall: skip following when the anchor is on a vehicle
(Exile's Reach boar ride) so bots don't trail an on-rails ride.
- New OnPlayerVehicleExit hook (wired in the core-hooks patch at
Unit::_ExitVehicle): after the owner leaves a vehicle, teleport owned bots
to the owner's position and inherit the owner's PhaseShift so they actually
appear (bots were spawning at coords but not in the player's phase).
