Chunky - Au Naturel Edit

Summary of Changes to Chunky (Forge 1.20.1)

Deadlock & Threading Fixes

• Removed synchronized keyword from update() method - Was causing monitor deadlock between Chunky thread and server thread
• Added dedicated 4-thread callback executor - Handles chunk completion callbacks separately from server thread
• Changed whenComplete to whenCompleteAsync with callback executor - Moves heavy callback work off the server thread
• Added 60-second timeout on waiting for pending chunks - Prevents infinite hangs if chunks get stuck; logs warning and continues
• Added proper executor shutdown - Cleans up callback threads when task finishes

Resource Management Fixes

• Moved ticket cleanup to server.execute() - Schedules cleanup for next server tick instead of blocking completion chain
• Limited thread pool to max 10 threads - Was previously unbounded (could create unlimited threads)
• Added bounded queue (100 capacity) - Prevents task queue overflow

World Generation Bar Fixes

Wrapped  bar updates in server.execute() - Ensures thread-safe access to Minecraft's CustomBossEvents

• Wrapped boss bar cleanup in server.execute() - Fixes multiple progress bars appearing when running Chunky multiple times
