## Summary
`CLICOLOR_FORCE` changes the output of underlying build commands, which
messes with wrapper tools trying to parse their output.
Closes#12564, closes#15415.
Add support for `RUST_LOG` to the uv build backend. While we were
previously using logging statements in the uv build backend, they could
only be shown when when using the direct build fast path through uv, as
there was no tracing subscriber to write log messages out. This means no
debug logging when using the build backend through pip, `python -m
build`, an incompatible version of uv, or any other build frontend; No
option to figure why includes and excludes behave the way they do.
This PR closes this gap by adding a tracing subscriber. The only option
to enable it is `RUST_LOG`, as we don't have a CLI. The formatting style
is the same as for uv, and color is also support in the same way, albeit
only through anstream's support for TTYs and environment variables. We
recommend only `RUST_LOG=uv=debug` and `RUST_LOG=uv=verbose` in the
docs, but this can be used to debug into crates such as `glob`, too.

The Renovate config in this repository needs migrating. Typically this
is because one or more configuration options you are using have been
renamed.
You don't need to merge this PR right away, because Renovate will
continue to migrate these fields internally each time it runs. But later
some of these fields may be fully deprecated and the migrations removed.
So it's a good idea to merge this migration PR soon.

Allows pinning the Python build version via environment variables, e.g.,
`UV_PYTHON_CPYTHON_BUILD=...`. Each variable is implementation specific,
because they use different versioning schemes.
Updates the Python download metadata to include a `build` string, so we
can filter downloads by the pin. Writes the build version to a file in
the managed install, e.g., `cpython-3.10.18-macos-aarch64-none/BUILD`,
so we can filter installed versions by the pin.
Some important follow-up here:
- Include the build version in not found errors (when pinned)
- Automatically use a remote list of Python downloads to satisfy build
versions not present in the latest embedded download metadata
Some less important follow-ups to consider:
- Allow using ranges for build version pins
## Summary
We've received several requests to validate that installed wheels match
the current Python platform. This isn't _super_ common, since it
requires that your platform changes in some meaningful way (e.g., you
switch from x86 to ARM), though in practice, it sounds like it _can_
happen in HPC environments. This seems like a good thing to do
regardless, so we now validate that the tags (as recoded in `WHEEL`) are
consistent with the current platform during installs.
Closes https://github.com/astral-sh/uv/issues/15035.

## Summary
After chatting with the PyTorch team, it looks like some number of
wheels were accidentally uploaded with
`no-cache,no-store,must-revalidate` due to
https://github.com/pytorch/pytorch/pull/149218. They're going to correct
this for the respective wheels. I've encouraged them to set an immutable
caching header for these files, and it might happen. But even if this
isn't set, by default we only allow these wheels to be cached for 600s,
since the other wheels don't include a `Cache-Control` header at all
(but do include a `Last-Modified`, so we cache based on our heuristic:
`Freshness lifetime heuristically assumed because of presence of
last-modified header: 600s`). This probably leads to tons of unnecessary
downloads for users over time. Andrey from the PyTorch team agreed that
we should do this.
Closes https://github.com/astral-sh/uv/issues/15480.
## Summary
This is causing some cyclic dependencies issues for me, because these
can be used in virtually _any_ crate (like `uv-install-wheel`), which
then means that all of `uv-configuration` becomes a dependency, etc. I
think this should be a leaf crate so that we can safely depend on it
anywhere.
## Summary
Move the Resolver reference into a new Internals section in the
reference. Add the new nav item, fix internal linking to the new path,
fix server side redirect to the new path for external traffic via
redirect_maps, fix non existent anchor in
"docs/concepts/projects/dependencies.md"
Closes#15412

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Closes#14866. Adds a `no-install-local` flag to the sync and export
commands that excludes locally defined packages from being installed.
This helps with if you're caching your virtual environment. You can
exclude local packages since they're more likely to change between
builds.
## Test Plan
snapshot test: `sync::no_install_local`
CI
## Notes
I made an `InstallOptions` struct to avoid a crate isolation issue I was
running into while implementing.
Thanks for maintaining this project!
