v1.2.0 — Core Optimization Engine Update

Major performance overhaul introducing an async chunk-building pipeline, region-based multi-draw batching, dynamic occlusion culling, and custom GPU memory management.

New Features

Core Architecture

• OptimizationManager — Added central lifecycle coordinator to manage all optimization subsystems.
• FrameBudgetManager — Added adaptive frame timing using EMA tracking, targeting a 30% frame-time cap for GPU uploads.

Async Chunk Building

• ChunkBuilderTask — Added core interface for asynchronous chunk build tasks.
• ChunkBuilderMeshingTask — Added task to extract block/fluid geometry into compact vertex buffers.
• ChunkBuilderSortingTask — Added task to re-sort translucent quads based on camera distance.
• ChunkBuilderThread — Added dedicated worker thread to process background render tasks.
• ChunkBuildScheduler — Added priority-based task queue manager.
• TaskOutput — Added build result container for vertex and index data.

Visibility Culling

• OcclusionCuller — Added BFS graph traversal combining frustum and fog culling.
• SectionTree — Added spatial tree structure for low-overhead visibility queries.

Render Region Batching

• RenderRegion — Added 8x4x8 section grouping with multi-draw batching and buffer arena support.
• RenderRegionManager — Added region lifecycle management, GPU upload routing, and cache invalidation.

Memory Management & Storage

• GlBufferArena — Added custom GPU memory sub-allocator with free-list allocation and block merging.
• SectionStorage — Added concurrent section container powered by ConcurrentHashMap.

Thread-Safe World Snapshots

• LevelSliceView — Added thread-safe read-only world snapshot for off-thread building.
• ClonedChunkSectionCache — Added LRU cache for cloned chunk section data.

Changes & Improvements

• fork-client.mixins.json — Registered fog and level extraction mixins.
• ForkClientClient.java — Integrated OptimizationManager startup initialization and auto-reload on world disconnect.
• FogRendererMixin.java — Intercepted fog parameters to feed occlusion culling.
• LevelExtractorMixin.java — Intercepted block state updates to trigger instant section re-renders.
