#3880 fixed the nested list[dict] → Root() bug by adding _object_schema_to_type and wiring it into the recursive _get_from_type_handler. The top-level json_schema_to_type entry point and the anyOf dict-in-union branch continued to carry their own hand-rolled copies of the same four-case object-schema logic. That was the divergence risk that produced the original bug, and leaving two copies around means the next change to object-schema handling has to remember to touch three sites.

This PR collapses all three sites into the existing helper. The top-level branch becomes a single call (passing name through so explicit top-level names still override schema.get("title")), and the anyOf special case is deleted outright — _schema_to_type already routes object subschemas through the helper, so the hand-rolled dict-in-union handling is now redundant. No behavior change, verified by the existing 863-test suite including the 229K real-world schema fuzz (same 279-baseline SchemaError count, zero crashes introduced).

# Before: three near-duplicates of the four-case logic
# After: one helper, called from both entry points

if schema.get("type") == "object":
    return _object_schema_to_type(schema, schemas=schema, name=name)

Closes #3882.
