chore: align MuJoCo dependencies with 3.10

[lntutor]

Summary

• align the bridge runtime pin with the URLab plugin MuJoCo 3.10 baseline
• update the mjlab mujoco-warp pin to the compatible 3.10.0.3 release
• add a metadata regression for both public dependency constraints

FixesURLab-Sim/UnrealRoboticsLab#78.

Testing

• uvx pytest tests/test_project_metadata.py -q
• uvx ruff check pyproject.toml tests/test_project_metadata.py
• uvx ruff format --check tests/test_project_metadata.py

uv sync --extra dev is currently blocked before test execution because the repository pin for the editable RoboJuDo submodule cannot be checked out (the pinned commit is unavailable from its configured remote). The focused metadata test uses an isolated runner and does not require that submodule.
