Adds validation/validate_mtlx.py and a GitHub Actions workflow that validates reference/open_pbr_surface.mtlx and all examples/*.mtlx on every PR or push that touches .mtlx files. The validator uses pip-installed MaterialX (materialx on PyPI) for zero dependency setup. It also performs an explicit nodename reference check on the standalone document to catch dangling connections that with-libraries validation misses when a file shares a name with a standard library file.

Summary
validation/validate_mtlx.py, a script that validates.mtlxfiles against the MaterialX standard libraries.github/workflows/validate-mtlx.yml, which runs the validator onreference/open_pbr_surface.mtlxand allexamples/*.mtlxon every PR or push that touches.mtlxfilesHow it works
The validator uses
pip install materialx(no build-from-source required), loads the standard libraries, and runsdoc.validate(). It also performs an explicit nodename reference check on the standalone document — this catches dangling connections that the with-libraries validation misses when a file shares a name with a standard library file (asopen_pbr_surface.mtlxdoes withlibraries/bxdf/open_pbr_surface.mtlx).Test plan
