Bug fixes:

• ViewDistanceAdjuster: sort TPS tiers ascending so the correct severity level is applied regardless of config order
• ChunkManager: always prune stale access map entries on every sweep (previously only pruned at >50k entries, allowing indefinite accumulation)
• VillagerOptimizer: replace O(n) entity scan in breed event handler with cached count from sweep task — eliminates main-thread stall on every breed event
