"New Model" should directly open a model, instead of there being an intermediate "new model" page

• x Is new feature

Description of suggestion or shortcoming:

This would be some more work, but would be good for convenience. Not sure what initial URL to use. If we have enough time/content before saving, we could use an LLM to suggest a name.

Maybe we start with a random hash or something.

I imagine it's fine to start private & personal.

It would overall be great if we could make "Quickly creating and saving a model" a really fast thing.

We could also not warn people about changing the name, if there aren't any exported variables anyway.
