Champions Optimization

Patches for performance optimization and stability enhancement
Better user experience！

Detailed optimization and fixes are as follows:

[Fix] Issue where packet tags fail to take effect on initial launchFixed the problem that queries for deny_champions and bosses tags return empty results during the early server startup phase. Eligibility evaluation construction now runs after packets are fully loaded, ensuring tag exclusion/capping configurations work correctly from the first generation

[Fix] Thread safety risks triggered by /reloadThe filter collection is refactored to use volatile references plus copy-on-write logic, eliminating extremely rare concurrent modification exceptions during configuration reloading

[Improvement] Instant activation of configuration changesAfter modifying Champions Fix configurations in-game via the /config command, eligibility evaluation will automatically rebuild without running /reload or restarting the server.
