Ln 611 Docs Structure Auditor

This is a specialized documentation auditor that checks eight structural quality dimensions: hierarchy and links, single source of truth, proactive compression, requirements compliance, freshness indicators, legacy cleanup, stack adaptation, and import pattern compliance. It scans all markdown files in your project, builds a hierarchy from AGENTS.md when present, and returns a scored report with severity-tagged findings including file and line numbers. Useful when you need to enforce documentation standards across a codebase, especially in teams where docs tend to drift, duplicate, or accumulate legacy content. The compression enforcement is notable: it treats size limits as ceilings, not targets, and flags verbose content even when under the limit.
