fix: avoid repo name collision for multi-version packages in uv.lock

[roundhd]

Summary

When uv.lock contains multiple versions of the same package (e.g., python-version-conditional deps like ipython 8.x for py3.9 and 9.x for py3.13), _sbuild_repo_name and _whl_install_repo_name produce identical repo names, causing collisions.

Changes:

• Include sha1(version)[:8] in _sbuild_repo_name and _whl_install_repo_name for disambiguation
• Pass full package dict (with version) in _group_repos instead of {"name": package}

Fixes #792

Hey @roundhd, thanks for the contribution!

I don't believe this is a complete solution to the problem, since this original implementation of the module extension lacks the decision machinery to correctly handle multiple versions of a locked package. This and the need to correct extras handling is the driver behind #778, which has at this point turned into a near rewrite of the extension to handle all the relevant graph details. That should be coming shortly.
