The two monolithic XSD content/identity rules only satisfied the OpenAPIKit validation idiom at the wrong granularity: no per-constraint removability, no isolable failing/near-miss tests. Split them into 32 named rules, each finding tagged at its origin and cached per XSDContext so the walk still runs once per document (the #101 decision against duplicating XSD's recursive type resolution still holds). Wired the streaming path's ID/IDREF and identity checks through the same framework instead of calling the validators imperatively, and added the unwrapAndLookup combinator the rule already named as required. Also includes the mandated repo-wide swiftformat/swiftlint pass.
