add branch/tag support [wip]

[wolfv]

Just tried this. Looks like it kinda works? - For lockfile validation I am not sure yet. Maybe we can store the requested URL somehow?

Did you try seeing if the VerbatimUrl in the resolves still contains the correct given? The problem was that in an older version 'uv' was overwriting the given url when a branch or tag was used.

I think this still seems to be the case because the lock file of the example did not change? Or maybe it was not committed.

I don't see the tag being recorded in the direct_url.json. I am not sure where we would get the VerbatimUrl back. However, since we know the original requirement, I am wondering if we can not just insert that in the lockfile as URL ... with the branch. And the resolved requirement + Git hash would be stored in the package object. So that it looks something like:

osx-arm64:
- git+https://bla.com/requests.git@87d63de8739263bbe17034fba2285c79780da7e8?branch=v2.29.0

...

And later.

- name: requests
  version: 2.29.0
  url: git+https://github.com/psf/requests.git@87d63de8739263bbe17034fba2285c79780da7e8

So the idea here is currently:

• we back-reference the original requirement. We use the name here. That means that users will have to use the proper names on the left-hand side
• At thsi point the URL is already python-formatted wtih an @..., we just split off the original request and insert it as the query string in the URL we use for the lockfile.

I think this could work quite nicely because we can easily ignore the query string when testing for up-to-date-ness of the environment. And when check if the requirements have changed, we could also have some special code that checks the ?request=....
