Fixes workspace member detection to properly handle shared path prefixes

[edgarrmondragon]

Workspace member resolution was mishandling cases where the main project and the member shared a partial directory name (e.g. 'path/to/local_app' and '/path/to/lib_member' share the 'l' string in the last part of the path), it would return an invalid path like '/path/to/l' of the true common ancestor directory. os.path.commonpath correctly returns the nearest common directory, which is what we need as the base for the member glob search.

This is also why os.path.commonprefix will be deprecated in Python 3.15:

• gh-74453: Deprecate os.path.commonprefix python/cpython#144436

@cjames23 the CI failures are unrelated and I believe they were introduced by #2188:

S607 Starting a process with a partial executable path
  --> scripts/release_github.py:20:24
   |
18 |     # Create and push tag first
19 |     try:
20 |         subprocess.run(["git", "tag", tag], check=True)
   |                        ^^^^^^^^^^^^^^^^^^^
21 |         subprocess.run(["git", "push", "origin", tag], check=True)
22 |         print(f"Created and pushed tag: {tag}")

I can submit a PR adding the two needed noqa Ruff comments to ignore the start-process-with-partial-path errors, if you don't have a different fix in mind.

I have a fix coming shortly

Can you rebase and merge? I am about to cut a release for hatch and if you can get this updated inside the release tag for the next release I will include these updates as well.

[edgarrmondragon]

I can rebase it, but the branch is up to date, so I'm not sure what you mean.

[cjames23]

LGTM. I will get this included with the next release a little bit later today. Thank you for finding this and helping!
