v3 stretch: vscode.lm-powered ambiguity scoring

The curated pattern library (and, with a license, the curated contradiction-pair list) is what ships today. A further step — scoring arbitrary, not-yet-catalogued phrasings for ambiguity and proposing rewrites using vscode.lm — is intentionally not implemented. It's called out here as an honest roadmap item: it would need a model-backed pass over each rule file, careful prompt design to keep false positives low, and a way to review suggested rewrites before they land, all of which are future work.
