SSWorld 0.24.0 — Ray-traced GI and Lumen Gallery

SSWorld 0.24.0 adds opt-in WebGPU software ray tracing and global illumination (GI), with an English Lumen Gallery showcase.

• Compare GI on/off with fixed lights, materials and camera; explore the sculpture and furnished lounge.
• Change the engine clock between 16:00 and 22:00 for sun-driven day/night lighting.
• Follow the updated skill, catalog notes and GI usage guide for startup preparation, readiness, toggles and troubleshooting.
• Page refreshes restart GI preparation. Cold pipeline compilation can take tens of seconds; optional same-page resource retention does not remove this cost.
• Update texture-memory, model, instancing and Tileset budget handling, preview support and Windows test compatibility.

Lumen Gallery is the demo name; this is not an Unreal Engine Lumen integration, hardware RT or frame generation. Ordinary starter scenes keep GI disabled by default.
