esBuild serverless (#14886)

Use [esbuild](https://esbuild.github.io/) to Build serverless entire

folders can contain code organized in folders

## Small example

This now works:

<img width="1330" height="686" alt="image"
src="https://github.com/user-attachments/assets/e0639517-492d-4b64-8722-18bbe94dacb0"
/>
