Audit and reorganize a project's docs/ folder by categorizing every file (Cat 1 delete / Cat 2 archive / Cat 3 stale-flag / Cat 4 active), proposing a version-first layout with a docs/archive/ subtree, and applying changes only after explicit user confirmation. Use whenever the user says "clean up docs", "reorganize docs", "archive old docs", "docs folder is messy", "audit docs", "refactor docs structure", "the docs are cluttered", "review docs before release", or before a version bump. SKIP for content accuracy fixes (use update-documentation), repo-root layout changes (use refactor-project-layout), or CHANGELOG generation (use generate-changelog).
