 * This function is called at runtime for each field. It handles recursive schemas where the
 * pre-expansion in `expandUiSchemaDefinitions` couldn't go deeper.

 * When the schema contains a `$ref`, this function looks up the corresponding uiSchema definition
 * from `registry.uiSchemaDefinitions` and merges it with any local uiSchema overrides.
 *
 * Resolution order (later sources override earlier):
 * 1. `ui:definitions[$ref]` - base definition from registry
 * 2. `localUiSchema` - local overrides at current path
 *
 * @param schema - The JSON schema (may still contain `$ref` for recursive schemas)
 * @param localUiSchema - The uiSchema at the current path (local overrides)
 * @param registry - The registry containing `uiSchemaDefinitions`
