/doc-check — run document conformance

1. Run it:
   • Governance baseline (with known-findings baseline): make doc-check
   • A specific file or directory: uv run python -m koa.workflows.doc_check <path> (add --baseline architecture/evidence/doc-check-known-findings.json when checking architecture/governance/)
2. Explain each failing finding in plain language and what would fix it. The checks: title_present (level-1 heading first), status_present (**Status:** marker), date_present (**Date:**/**Prepared:**), heading_step (no level jumps), links_resolve (relative links exist).
3. Rules:
   • Documents under architecture/governance/ are committed verbatim — never edit them to silence findings. If a finding is accepted as-is, add it to architecture/evidence/doc-check-known-findings.json with a one-line rationale in the commit message.
   • For any other document, prefer fixing the document.
4. Remember this workflow is a placeholder (ADR-KOA-DEV-001), not Kūkulu — don't grow it new check types without an ADR.
