      • Function: executeFunctionCall()

      executeFunctionCall(processor: MessageProcessor, fn: object, surfaceId: string, dataContextPath?: string, options?: ResolveFunctionOptions): unknown

      Resolve arguments, look the function up in the registry, and invoke it. When no impl is registered, log once and return undefined so callers (checks, dynamic-property bindings) can degrade gracefully.
