[2026-05-19]

Streamlined the contributor workflow behind a top-level Makefile: make install for one-time setup, make check for lint/format/license/XML, make test for the simulation suite, make all for everything CI runs. Slimmed the PR template and rewrote the CONTRIBUTING dev-setup section to match. Removed the redundant check_license.yml workflow (its job is already covered by the pre-commit workflow).

Added format_xml.py, an XML formatter for MJCF files (2-space indent, 120-col wrap, single-line attribute values). Wired into pre-commit so the same check runs locally and in CI. Reformatted every existing XML in the repo so the rules are now actually enforced.
Added pre-commit hooks (ruff lint+format for Python, trailing-whitespace and EOF fixers, license check) with a matching CI workflow. Contributors can install locally with uv tool install pre-commit && pre-commit install. Excludes .patch and .ipynb files.
Removed the MJX column from the README model tables and dropped the MJX test from CI. MJX-compatible XMLs are still shipped per-model.
Added a CI lint that every model directory ships a README, LICENSE, CHANGELOG, and scene*.xml, and that CONTRIBUTORS.md stays sorted. Backfilled missing changelogs and renamed rainbow_robotics_rby1/LICENSE.txt to LICENSE.
