Subject: [PATCH] Apply GH-DEC-2026-017 and GH-DEC-2026-020 to the layer
 declaration.

This repository never received GH-DEC-2026-017 (gate-house's gap, recorded
in GH-DEC-2026-020), so both rulings land here together.

- INTENT.md frontmatter: remove standard_version: "0.7" (017 section 5) and
  de-version the standard: path to net-kingdom/canon/standards/
  security-layer-model (020 section 1). layer: Staff is unchanged and
  INTENT.md remains the declaration (017 section 1); no layer.yaml added.
- tests/test_layer_declaration.py: stop asserting the old
  standard_version; case-fold the layer comparison (017 section 2); fail if
  any frontmatter key or value carries a standard or companion version,
  including a versioned standard: path or companion_version (020 sections
  1-2); comments are not reached. Known-bad forms are exercised.

conformance_state is left untouched pending gate-house's open question.
