Wix App Registration

After creating any extension file, you must update the main src/extensions.ts file to register the extension with the app.

Why Registration Matters

Service plugins won't be called during checkout flows

Event handlers won't receive webhook deliveries

Embedded scripts won't be injected into site pages
