graybeard-audit

Whole-repo audit for over-engineering. Like graybeard-review, but scans the entire codebase instead of a diff: a ranked list of what to delete, simplify, or replace with stdlib/native equivalents. Use when the user says "audit this codebase", "audit for over-engineering", "what can I delete from this repo", "find bloat", "graybeard-audit", or "/graybeard-audit". One-shot report, does not apply fixes.
