Prepare Methodology 7.0.0

[transitrix]

What changed

Prepare Methodology 7.0.0: synchronize catalogue pins and coverage presets, update changed specification versions, and collect release notes for requirement reports, numeric risk authoring, provenance and modelling guidance. The major boundary activates ACTION numeric lower bounds.

The 6.0→7.0 recipe changes only the manifest pin. Its read-only Python/PyYAML postcheck reports invalid numeric ACTION values in declared zones and supported inline collections without rewriting model data or diagnostic history. It is explicitly not whole-model certification.

How it is verified

• Notation lint, ADL, plugin manifest and skill conformance checks passed.
• 120 notation, vocabulary and migration regression tests passed.
• Focused checks passed for dry-run, CRLF/comment preservation, only-pin mutation, idempotence, all six negative fields, invalid score types, duplicate YAML, inline values, symlink and unsupported-pin refusal.
• Release fixture postcheck passed.

Companion adopter update and exact-commit draft preparation remain separate release steps. No publication is performed by this PR.
