docs-sync

@microsoft

Diff src/ and .github/ against docs/ to detect drift between code and design spec. Use when auditing the docs folder, after merging structural changes (adding paths/modules/diagrams/syntax/agents/skills/hooks), or before a release. Use for questions like "is docs in sync?", "what changed since the last docs update?", "find docs drift". Produces a structured report with proposed edits — does not modify docs/ directly.
