Forge bundle resolution

Play needs a forge dist/<ver>/ bundle (mujoco.js + mujoco.wasm).

The dev server mounts:

• /mujoco-wasm-play/ → this repo root

• /forge/ → a sibling ../mujoco-wasm-forge checkout if present (otherwise falls back to this repo root)

• /mujoco-wasm-forge/ → legacy alias for a sibling forge checkout (if it exists)

So on localhost, Play can fetch forge artifacts from:

/forge/dist/<ver>/

If you want to point at a different bundle, pass forgeBase=:

http://127.0.0.1:8000/index.html?model=raj&forgeBase=/forge/dist/3.5.0/
