Iris/Oculus Atmosphere

Added

• Terralith and Nature’s Spirits biome support, enabling the forecast, humidity, and sunlight models to recognise these worldgen packs out of the box.

Fixed

• Improved weather stability logic to avoid rapid cloud cycling or “rave” behavior between biomes.
• Corrected humidity-to-rain intensity mapping to produce smoother transitions.
• Cloud region spawning no longer stalls behind stuck async workers, preventing empty skies on fresh worlds.

Changed / Removed

• Forecast updates now occur asynchronously, ensuring seamless regional transitions and no TPS impact during major weather changes.
• Forecast curves were rebalanced to keep daytime highs/lows anchored to realistic seasonal envelopes before wind, humidity, and storm modifiers are applied.
