Problem

mermaid compile failures still fall back to generic notifications for real parse errors, and the old parser can greedily capture source excerpts or stack traces instead of the actual Expecting ... got ... payload from current mmdc output.

Solution

Add a mermaid failure_summary that only summarizes trusted parse-error shapes, tighten the diagnostic parser to use the same anchored matches, and update the fixtures and specs to cover noisy parse output and conservative fallback cases. Closes #97.
