Debug MatcherPass Skill

An end-to-end workflow for diagnosing why an OpenVINO MatcherPass-based transformation does not fire on a given model.

Goal

Produce two deliverables before finishing:

1. Diagnosis report — post in the chat using the template at the end of this skill. Do not save it to a file.
2. Reproducer test — edit the existing test source file to add the new TEST_F case, then compile and confirm it reproduces the non-firing behavior.

The only filesystem change should be the test file edit. Do not create additional output files.

Early exit — all passes fired: If Step 2a shows CALLBACK SUCCEDED > 0 for every pass under investigation, skip Steps 3–6. Post a lightweight confirmation summary (use the "all fired" variant in the Diagnosis Report Template) and do not write a reproducer test. There is no bug to reproduce.
