cp312/cp313/cp314t all hung at the exact same point (render_test.py's setUp creating a second mujoco.GLContext via GLFW) and were killed only by the 360-minute job timeout - not a slow build, a genuine hang, as each build had already reached the test phase within ~70 minutes. Upstream's own CI sets MUJOCO_GL: disable for its "Test Python bindings" step precisely to skip GLContext-dependent tests on headless runners; mirroring that here removes the hang instead of masking it with a bigger timeout.

mujoco3.12.0Compiles the MuJoCo physics engine plus its pybind11 Python bindings, using upstream's own two-stage CMake flow (core library, then bindings against it) rather than cibuildwheel. Upstream publishes no riscv64 wheel.
