Generating an array whose items reference a named definition with a type array or with oneOf but no scalar type exits with Unknown type of object. The type-string renderer already supports these unions, but generateObject() rejects them before it reaches that renderer.

Route oneOf and array-valued type definitions through the existing type-alias generation path before the scalar-type switch. Referenced branches keep their generated definitions and imports, and ordinary object definitions continue to produce interfaces.

Added six generator regression cases covering type[] with and without oneOf, oneOf with and without a scalar type, referenced union branches, and ordinary object interfaces. The new failure cases were reproduced against the previous implementation before applying the fix.

Validation:

• yarn test — passed (includes Jest, TypeScript checks, ESLint, and formatting).
• yarn build — passed.
• Generated mixed scalar/object/array union typings and compiled the emitted entry point with tsc --noEmit --strict --skipLibCheck — passed.

Package release and downstream dependency updates are outside this PR.
