Optimization & Update Checker Release v2.1

• Optimized Physics Checks: Replaced expensive Bukkit event.getBlock().getChunk() calls inside LagListener with fast bit-shifted coordinates (block.getX() >> 4).
• Memory Leak Prevention: Decoupled chunk tracking maps from strong org.bukkit.Chunk references using a custom ChunkKey class, allowing unloaded chunks to be GC'd.
• Load-Spreading Scanner: The entity culler now spreads its chunk scanning workload across ticks (processing batches of 50 per tick) to eliminate main-thread TPS micro-stuttering.
• Update Checker: Integrated an asynchronous update checker checking GitHub releases.
