This PR modifies the source distribution building to replace any
existing targets after building the new wheel. In some cases, the
existence of an existing target may be indicative of a bug, so we warn.
It's partially a workaround for some (but not all) of the errors in
https://github.com/astral-sh/puffin/issues/554.
## Summary
This PR unifies the behavior that lived in the resolver's `distribution`
crates with the behaviors that were spread between the various structs
in the installer crate into a single `Fetcher` struct that is intended
to manage all interactions with distributions. Specifically, the
interface of this struct is such that it can access distribution
metadata, download distributions, return those downloads, etc., all with
a common cache.
Overall, this is mostly just DRYing up code that was repeated between
the two crates, and putting it behind a reasonable shared interface.
## Summary
This crate only contains types, and I want to introduce a new crate for
all _operations_ on distributions, so this feels like a more natural
name given we also have `pypi-types`.
The need for this became clear when working on the source distribution
integration into the resolver.
While at it i also switch the `WheelFilename` version to the parsed
`pep440_rs` version now that we have this crate.
This PR modifies the `install-wheel-rs` (and a few other crates) to get
everything playing nicely. Specifically, CI should pass, and all these
crates now use workspace dependencies between one another.
As part of this change, I split out the wheel name parsing into its own
`wheel-filename` crate, and the compatibility tag parsing into its own
`platform-tags` crate.
This PR copies over the `pep440-rs` crate at commit
`82aa5d4dcbe676b121dc931b0afa09a82de8e3d7` with no modifications.
It won't pass CI, but modifications will intentionally be confined to
later PRs.
