fix(core-eslint): parse satisfies-shaped manifests; unify manifest parser

A manifest written as `{...} satisfies FeatureManifest` (or the combined
`as const satisfies` idiom) parsed to null, silently no-oping the
error-level conformance rules. unwrapAsConst now strips TSAsExpression
and TSSatisfiesExpression in a loop. The file also carried a verbatim
second copy of its own parser for parseManifestFully; both public entry
points now share one implementation. The template's field set (audits,
rateLimit, requiresConsent) is preserved.
