Widen A12 enforcement from the key name to the declaration's content (GH-DEC-2026-020).

internal/layer/conformance.go enforced A12 as "no key named standard_version",
and so could not see the same pin as a versioned standard: path or as
companion_version. It now detects a version of the standard or its companion
in any key or value of the declaration (INTENT.md frontmatter, layer.yaml),
including a version in a path, and excludes comments and schema_version. It
refuses to be applied to pep-stance.yaml, pip-claims.yaml or
evidence-classification.yaml, which A12 r2 does not reach (§3).

Every run of check_layer_conformance and of the estate survey now prints the
standard version it checks against (layer.ValidatedAgainst, kings-guard's
pattern) and its scope (§4). The survey applies the same detection to peers'
declarations; the receipt is refreshed because the survey's output changed
(no peer declaration currently carries a version).

Tests fail if a versioned standard: path or a companion_version comes back.
flex-auth's own INTENT.md needed no change.
