RoadmapSmith Audit

Use this command when the user wants the post-sync mismatch summary after applying evidence-backed checklist updates.

Required behavior

1. Prefer the local engine inside this repository:
   • node roadmap-skill/bin/cli.js sync --audit --project-root .
   • on this Windows machine, prefer C:\Program Files\nodejs\node.exe roadmap-skill/bin/cli.js sync --audit --project-root . if node is not in PATH
2. Otherwise prefer roadmapsmith sync --audit --project-root ..
3. Explain that this is the current sync-plus-audit flow, not a standalone read-only audit engine.
