Fix test to avoid importing swc.config.js in Jest

The test was importing swc.config.js which requires Node.js modules (path, fs)
that aren't available in Jest/browser environment, causing build errors.

Changed to a documentation-style test that explains the required SWC
configuration without requiring the config file at runtime.
