Summary

• Adds installed-user uselesskey doctor with text and JSON output.
• Checks CLI version, current directory, target write access, default output path safety, JSON output support, and known profiles.
• Keeps the command scoped to installed CLI concerns without repo-local proof tools or generated fixture payload inspection.
