[X3D-Ecosystem] X3D JSON with WebGPU

[John Carlson]

My version currently generated what looks to be correct X3D JSON (I added
metadata after the generation), and is validated with hyperjump-io.   It
does say the json is invalid still.  I’m working on making the errors
easier to read with hyperjump-io/json-schema-errors soon.  I kind of miss
the familiar Ajv.  There’s an outstanding WIP pull request to handle oneOf
subschemas, so I’m waiting
https://github.com/hyperjump-io/json-schema-errors/pull/159

I will try to switch from vite to something that can run on a static site,
I don’t know if vite has that feature or not.

The conversion of the JavaScript processing looks like it went well without
lots of pain, so that’s a positive!
