The uv-performance-memory-allocator is currently optimized out at least
on musl due to the crate being otherwise unused
(https://github.com/rust-lang/rust/issues/64402), causing musl to not
use jemalloc and being slow.
Command:
```
cargo build --target x86_64-unknown-linux-musl --profile profiling
hyperfine --warmup 1 --runs 10 --prepare "uv venv -p 3.12" "target/x86_64-unknown-linux-musl/profiling/uv pip compile scripts/requirements/airflow.in"
```
Before:
```
Time (mean ± σ): 1.149 s ± 0.013 s [User: 1.498 s, System: 0.433 s]
Range (min … max): 1.131 s … 1.173 s 10 runs
```
After:
```
Time (mean ± σ): 552.6 ms ± 4.7 ms [User: 771.7 ms, System: 197.5 ms]
Range (min … max): 546.4 ms … 561.6 ms 10 runs
The `cdylib` was used for the pyo3 bindings to uv-pep508, which don't
exist anymore. It was now creating warnings on musl due to musl
(statically linked) no supporting shared libraries.
## Summary
This follows Ruff's design exactly: you can provide a version specifier
(like `>=0.5`), and we'll enforce it at runtime.
Closes https://github.com/astral-sh/uv/issues/8605.
## Summary
Allows uv to recognize the ARMv5TE platform. This platform is currently
supported on Debian distributions. It is an older 32 bit platform mostly
used in embedded devices, currently in rust tier 2.5 so it requires
cross compilation.
Fixes#10157 .
## Test Plan
Tested directly on device by applying a slightly different patch to tag
0.5.4 which is used by the current Home Assistant version (2024.12.5).
After the patch Home Assistant is able to recognize the Python venv and
setup its dependencies.
Patched uv was built with
```
$ CARGO_TARGET_ARMV5TE_UNKNOWN_LINUX_GNUEABI_LINKER="/usr/bin/arm-linux-gnueabi-gcc" maturin build --release --target armv5te-unknown-linux-gnueabi --manylinux off
```
The target wheel was then moved on the device and installed via pip
install.
## Summary
Closes#7913 by adding an optional `--description` argument to `uv init`
that fills the description field in the pyproject.toml with the supplied
arg value.
Updated `uv init` docs to describe this new optional argument.
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
Added snapshot tests in `uv/crates/uv/tests/it/init.rs` to test this
functionality.
<!-- How was it tested? -->

## Summary
`uv run --exact` will remove any unnecessary packages prior to running
the given command. (By default, `uv run` uses "inexact" semantics.)
Closes https://github.com/astral-sh/uv/issues/7838.

## Summary
This PR solves an issue on Windows that platform-specific paths are
written to the `RECORD` file when installing, which is inconsistent with
PEP 376, quoting:
> Each record is composed of three elements:
>
>the file’s path
> * a ‘/’-separated path, relative to the base location, if the file is
under the base location.
> * a ‘/’-separated path, relative to the base location, if the file is
under the installation prefix AND if the base location is a subpath of
the installation prefix.
> * an absolute path, using the local platform separator

## Summary
This PR introduces a `LockTarget`, which is peer to `InstallTarget` and
enables us to capture the common functionality necessary to support
locking.
For now, to minimize changes, only the `Workspace` target is
implemented. In a future PR, I'll add a `Script` target for both locking
and installing.
## Summary
The proximate motivation is that I want to add new variant for scripts,
but `uv-resolver` can't depend on `uv-scripts` without creating a
circular dependency. However, I think this _does_ just make more sense
-- the resolver crate shouldn't be coupled to the various kinds of
workspaces, and these details are mostly encoded in `projects/lock.rs`
and similar files.
## Summary
This is necessary for some future improvements to non-`[project]`
workspaces and PEP 723 scripts. It's not "breaking", but it will
invalidate lockfiles for non-`[project]` workspaces. I think that's
okay, since we consider those legacy right now, and they're really rare.
