Fix GeoLite crash, add PerfMode profiling, reload cache invalidation

- GeoLite/MaxMind lookup wrapped in try/catch and disabled for the session on failure
  (stops the per-tick exception spam when the assembly cannot load during hot-reload)
- New PerfMode config option: writes performance logs to logs/perf_<date>.txt
  (DisableAll/SetSkill/PlayerDeath totals, per-skill SkillAction timings,
  aggregated OnTick/CheckTransmit avg-max summaries)
- css_reload now invalidates the skill-info and freeze-time caches
- Removed the last null-forgiving player lookups (Command, Armored, Baseball,
  FriendlyFire, OneShot)
