+- BoxLang `$ref` parse hangs / bad absolute paths: depend on `swagger-sdk` with cycle-safe walks, absolute path resolution, and no `isStruct(cfc)` on nested parsers (see coldbox-modules/swagger-sdk).
+- BoxLang: treat `arrayContainsNoCase` as boolean in `OpenAPIConstraintsGenerator` (do not compare with `> 0`; BoxLang evaluates `false > 0` as true).
