Studied Kimi's AI World Builder (Kimisworld.zip, issue #870):
- React + Three.js app with runtime code generation via new Function()
- WorldObject schema: type, geometry, material, color, position, rotation,
scale, animation string
- AI agent avatar with lerp-based movement, mood-based color, pulsing core
- State managed via Zustand; Bloom + ChromaticAberration post-processing
Adds ThreeJSWorldAdapter stub that maps Kimi's WorldObject schema to the
WorldInterface contract (observe/act/speak), documenting the HTTP/WS wiring
needed to bridge the Three.js app to Timmy's agent infrastructure.
The adapter's _object_to_entity_description() helper converts WorldObjects
into PerceptionOutput entity strings compatible with any WorldInterface
consumer, including the Morrowind integration.
