VO: True Sleep

[1.3.23+26.2]

Changed

• Zero-Allocation Mob Stasis Hot Loop: Refactored MobMixin.java with a static EntityType<?> worker tag cache and sentinel-based dynamic GameRule lookup, eliminating Optional allocations and registry holder sweeps during sleep warp.
• Fast-Path Ticker Acceleration: Refactored LevelMixin.java to pre-classify machine block entity types directly from ticker type strings, avoiding chunk block entity lookups for non-production blocks.
• Empty Potion Effect Fast-Path: Added .isEmpty() guard to LivingEntityMixin.java and MobMixin.java effect aging loops to eliminate iterator allocations on effectless entities.
