Transform output schema to TypeScript types with dotwalk support for reference columns.
Each output field that is a reference column will have dotwalk access to the referenced table's fields.
Note: FlowObject and FlowArray do not support ReferenceColumn, so they use standard type inference.
IMPORTANT: Check FlowObjectType and FlowArrayType FIRST before Column to avoid structural type matching issues.
