v0.0.0-beta.21

Changes

• Fixed MC 26.1.2 compatibility: Updated all client mixins for Minecraft 26.1.2 rendering pipeline changes (Camera.setup → extractRenderState, LevelRenderer.renderLevel new signature, EntityRenderDispatcher.shouldRender, etc.)
• Camera override: Injects into Camera.extractRenderState() instead of removed setup(), writes directly to CameraRenderState for reliable render pipeline override
• Entity rendering: Uses EntityRenderDispatcher.shouldRender() instead of removed render() for hiding local player during body camera
• Screen effects: Updated renderScreenEffect() signature to match MC 26.1.2 instance method
• Server mixins: Updated EntityMixin and ServerPlayerMixin with correct imports and disabled dead code paths
• Keyboard/Mouse input: Fixed method signatures for tick(), turnPlayer(), onButton()
• All remap=false: Uses direct method names with remap=false on all @Inject targets to fix Mixin AP obfuscation mapping errors in MC 26.1.2
