// Workaround, pending a CounterStrikeSharp release carrying the upstream fix: CSSharp's
// CCSPlayerController.Respawn() calls SetPawn(PlayerPawn.Value), which faults inside the engine's
// network-state change code when the pawn is DEAD — the usual respawn case — on the current CS2
// build (a bot respawned right after we kill it took the crash). This mirrors CSSharp's Respawn()
// but only re-attaches a LIVE pawn; the CCSPlayerController_Respawn vfunc re-creates the pawn on
// respawn regardless. Revert every SafeRespawn() call back to .Respawn() once the fixed package ships.
