Subject: [PATCH 1/2] refactor: extract tryResolveSingle helper in
 DefinitionCompiler

The resolvedType block had three near-identical if/else branches for AllOf,
OneOf, and AnyOf, each of which checked the collection for a single non-null
inline subschema and returned its type. Extract a shared helper and rewrite
the block using Option.orElseWith chaining:

- Eliminates ~25 lines of duplicate if/else logic
- Checks schemaObj.Type.HasValue first (most common case)
- Helper handles both null collection and missing-type cases

No functional change; all 417 unit tests continue to pass.
