This change updates the Emscripten build to output files named `mujoco.js`, `mujoco.wasm`, and `mujoco.d.ts` instead of `mujoco_wasm.*`. The internal CMake target name remains `mujoco_wasm` to avoid conflicts. The package name in `package.json` is also updated to `mujoco`. New enum tests are added.
