simple-rpg example assets v1

Prebuilt runtime assets for examples/simple-rpg (meshes, terrain, sky, audio, images).

Fetched automatically by examples/simple-rpg/scripts/fetch-assets.mjs (run via npm run setup / predev). Kept out of git to avoid binary bloat; regenerate the full set via the GameAssets pipeline.
