MineTracer

Changelog:

• Added minetracer$hasRelevantSlots flag to skip tracking entirely when no items are present
• Ultra-fast early exit if no container slots have items
• Quick container vs player inventory detection

• Pre-sized HashMap with typical chest size (27 slots) to avoid resizing
• Only store non-empty ItemStacks (most container slots are empty most of the time)
• Clear tracking map immediately after use to free memory

• Cache container position once per interaction instead of looking it up for each slot
• Skip empty-to-empty slot transitions entirely (most common case)
• Batch process only changed slots

• Only track container slots, never player inventory slots
• Skip processing if no relevant slots contain items
• Single pass through slots instead of multiple iterations
