[Request] Use type stripping for examples

[43081j]

We currently use jiti in the examples package in order to run the typescript sources.

In node 23.x, we can run these natively through node (i.e. node src/spinner.ts will work).

We could do this now but it means maintainers can only run examples under node 23, which may not be ideal (yet?).

We should at the very least enable erasableSyntaxOnly in our repo
