-  1. List unit-verification artifacts matching a rivet filter.

   2. For each, rivet-get the full artifact JSON.
   3. Extract fields.steps[].run as shell commands.
-  4. Run each command, capture exit code + duration.
-  5. Aggregate pass/fail per artifact.
-  6. Emit a Markdown summary suitable for posting as a PR comment.
