Lomka

Removed:

• Texture decode off-thread (LazyLoadedImageOffThreadMixin, virtual threads)
• Network compression buffer reuse (CompressionDecoderDirectInputReuseMixin)
• Shader program binary cache (config)
• LomkaConfigScreen (in-game config UI, 272 lines)
• CullingContext record
• AOT cache / compact headers logging
• UploadSizedRunnable (dead code)

Updated:

• EntityCullingMixin: removed 3 unused fields (~24 bytes saved per entity)
• LevelRendererAccess: removed dead method isSectionCompiledAndVisible
• EntityRendererCullingMixin: camera hash now uses hash3 (better distribution)
• FrustumMixin: infinite loop replaced with 256 iteration cap (fixes freezes)
• GL caches: call GL11 directly instead of GlStateManager (faster)
• GlRenderPassReuseMixin: collection clearing at HEAD instead of TAIL
• clientTickCullIncludeDisplay: false → true by default
