At a high level, this PR adds a smattering of new tests that
effectively snapshot the output of `uv lock` for a selection of
"ecosystem" projects. That is, real Python projects for which we expect
`uv` to work well with.
The main idea with these tests is to get a better idea of how changes
in `uv` impact the lock files of real world projects. For example,
we're hoping that these tests will help give us data for how #5733
differs from #5887.
This has already revealed some bugs. Namely, re-running `uv lock` for a
second time will produce a different lock file for some projects. So to
prioritize getting the tests added, for those projects, we don't do the
deterministic checking.
Add minimal support for workspace discovery, only used for determining
paths in the bluejay commands.
We can now discover the workspace structure, namely that the
`pyproject.toml` of a package belongs to a workspace `pyproject.toml`
with members and exclusion. The globbing logic is inspired by cargo. We
don't resolve `workspace = true` metadata declarations yet.
This script can compare different requirements between pip(-compile) and
puffin across python versions, with debug and release builds.
Examples:
```shell
scripts/compare_with_pip/compare_with_pip.py
scripts/compare_with_pip/compare_with_pip.py -p 3.10
scripts/compare_with_pip/compare_with_pip.py --release -p 3.9 --target 'transformers[deepspeed-testing,dev-tensorflow]'
```
It found a bunch of fixed bugs, e.g. the lack of yanked package handling
and source dist handling, as well as #423, which is currently most of
the output.
Example output:

Previously, we had two python interpreter metadata structs, one in
gourgeist and one in puffin. Both would spawn a subprocess to query
overlapping metadata and both would appear in the cli crate, if you
weren't careful you could even have to different base interpreters at
once. This change unifies this to one set of metadata, queried and
cached once.
Another effect of this crate is proper separation of python interpreter
and venv. A base interpreter (such as `/usr/bin/python/`, but also pyenv
and conda installed python) has a set of metadata. A venv has a root and
inherits the base python metadata except for `sys.prefix`, which unlike
`sys.base_prefix`, gets set to the venv root. From the root and the
interpreter info we can compute the paths inside the venv. We can reuse
the interpreter info of the base interpreter when creating a venv
without having to query the newly created `python`.
