Ecliptic Seasons

Mixin Infrastructure

• Introduced DirectInject and DirectExpression to reduce unnecessary object allocations generated by Mixin injections. Thanks to MixinLite for the inspiration.
• Added ConditionalMixin support to conditionally apply mixins based on the runtime environment.
• Converted several existing mixins to the new injectors or WrapWithCondition, significantly reducing object allocation rates in certain extreme scenarios.

Rendering Compatibility

• Added Embeddium-compatible color blending for seasonal foliage rendering.

Distant Horizons

• Refactored DHClientTool and DHTool, based on the improvements proposed by zerastos in #185.
• Improved seasonal snow coloring and frozen-water handling for distant LODs.
• Reduced temporary object allocations and improved thread safety.
• Enabled seasonal DH LOD updates by default for new users. This option can still be disabled if it causes stuttering.
• Seasonal colors in the LOD biome cache are now updated even when seasonal DH LOD updates are disabled.

Other Changes

• Fixed incorrect heightmap usage in BiomeHolder, which could cause stuttering while loading chunks.
