I found this while testing the tracking of marker expressions across
resolver forks. Namely, given
sys_platform == 'darwin' and implementation_name == 'pypy'
And:
sys_platform == 'bar' or implementation_name == 'foo'
These should be disjoint, but the disjointness checker was reporting
them as overlapping. I fixed this by giving handling of disjunctions
higher precedence than conjunctions, although I am not 100% confident
that this is correct for all cases.
## Summary
`normalize` now takes an owned value and returns `Option<MarkerTree>`,
such that if any sub-expression evaluates to `true`, we can normalize
out the entire marker.
Closes https://github.com/astral-sh/uv/issues/4267.
## Summary
Simplify and normalize marker expressions in the lockfile. Right now
this does a simple analysis by only looking at related operators at the
same level of precedence. I think anything more complex would be out of
scope.
