🔵 Needs a closer look

The .mlc.toml exclusion makes the existing validation job skip all docfx sources, leaving hand-written tutorials and analyzer documentation unchecked for broken links.

Restrict link-check exclusions to generated documentation output

.mlc.toml:7

mlc also reads .mlc.toml when invoked with CLI arguments, so the existing docs_validate.yml job will now skip every file under docfx, including the hand-written tutorials and analyzer documentation. The previous invocation did not exclude that tree, so broken links in the project's main documentation will silently stop being checked. Please restrict this exclusion to generated output rather than the documentation sources.
