XeroAntiCheat v1.0.9 bug fixes

- BUG-1: Added alerts.cooldown_ms (default 5s) to throttle warn() and
  sendAlert() in PunishmentManager, preventing chat spam during high-frequency
  flags. Verbose output in ViolationManager also respects the cooldown.
  Kick/ban punishments always fire immediately regardless of cooldown.
- BUG-2: Fixed FlyCheck false positive with Jump Boost I - condition was
  incorrectly flagging players with Jump Boost level 1. Now exempts all
  jump boost levels from the sustained-flight flag.
- BUG-3: Optimized SpiderCheck by caching player.getLocation() in a single
  variable instead of calling it 3 times.
