feat: Use org and url from tokens

[loewenheim]

The flow works like this:

1. In configure_args and Config::from_file, we read the token first. If it's an org token, we attempt to parse it and save the contained org and url. A malformed org token results in an error.
2. When we read a url or org (in Config::from_file, Config::get_org, Config::set_base_url), we check if we already have them from the token. If we do and the two values disagree, that's an error.

nice! Can't comment too much on the rust code, but logic seems great to me 👍 LMK once this has been released somehow, then I can update the bundler plugins to use this as well 🚀

[kamilogorek]

LGTM! Can we maybe get some integration tests around value mismatches?

[loewenheim]

You mean trycmd tests? Yeah, that's probably a good idea.

[kamilogorek]

Yup. It should be trivial to get them going with env vars

[loewenheim]

Don't even need env vars, unless you think I should explicitly try those as well.
