## Summary
This PR enables users to provide pre-defined static metadata for
dependencies. It's intended for situations in which the user depends on
a package that does _not_ declare static metadata (e.g., a
`setup.py`-only sdist), and that is expensive to build or even cannot be
built on some architectures. For example, you might have a Linux-only
dependency that can't be built on ARM -- but we need to build that
package in order to generate the lockfile. By providing static metadata,
the user can instruct uv to avoid building that package at all.
For example, to override all `anyio` versions:
```toml
[project]
name = "project"
version = "0.1.0"
requires-python = ">=3.12"
dependencies = ["anyio"]
[[tool.uv.dependency-metadata]]
name = "anyio"
requires-dist = ["iniconfig"]
```
Or, to override a specific version:
```toml
[project]
name = "project"
version = "0.1.0"
requires-python = ">=3.12"
dependencies = ["anyio"]
[[tool.uv.dependency-metadata]]
name = "anyio"
version = "3.7.0"
requires-dist = ["iniconfig"]
```
The current implementation uses `Metadata23` directly, so we adhere to
the exact schema expected internally and defined by the standards. Any
entries are treated similarly to overrides, in that we won't even look
for `anyio@3.7.0` metadata in the above example. (In a way, this also
enables #4422, since you could remove a dependency for a specific
package, though it's probably too unwieldy to use in practice, since
you'd need to redefine the _rest_ of the metadata, and do that for every
package that requires the package you want to omit.)
This is under-documented, since I want to get feedback on the core ideas
and names involved.

## Summary
This PR exposes uv's PEP 517 implementation via a `uv build` frontend,
such that you can use `uv build` to build source and binary
distributions (i.e., wheels and sdists) from a given directory.
There are some TODOs that I'll tackle in separate PRs:
- [x] Support building a wheel from a source distribution (rather than
from source) (#6898)
- [x] Stream the build output (#6912)
Closes https://github.com/astral-sh/uv/issues/1510
Closes https://github.com/astral-sh/uv/issues/1663.
## Summary
This PR revives https://github.com/astral-sh/uv/pull/4944, which I think
was a good start towards adding `--trusted-host`. Last night, I tried to
add `--trusted-host` with a custom verifier, but we had to vendor a lot
of `reqwest` code and I eventually hit some private APIs. I'm not
confident that I can implement it correctly with that mechanism, and
since this is security, correctness is the priority.
So, instead, we now use two clients and multiplex between them.
Closes https://github.com/astral-sh/uv/issues/1339.
## Test Plan
Created self-signed certificate, and ran `python3 -m http.server --bind
127.0.0.1 4443 --directory . --certfile cert.pem --keyfile key.pem` from
the packse index directory.
Verified that `cargo run pip install
transitive-yanked-and-unyanked-dependency-a-0abad3b6 --index-url
https://127.0.0.1:8443/simple-html` failed with:
```
error: Request failed after 3 retries
Caused by: error sending request for url (https://127.0.0.1:8443/simple-html/transitive-yanked-and-unyanked-dependency-a-0abad3b6/)
Caused by: client error (Connect)
Caused by: invalid peer certificate: Other(OtherError(CaUsedAsEndEntity))
```
Verified that `cargo run pip install
transitive-yanked-and-unyanked-dependency-a-0abad3b6 --index-url
'https://127.0.0.1:8443/simple-html' --trusted-host '127.0.0.1:8443'`
failed with the expected error (invalid resolution) and made valid
requests.
Verified that `cargo run pip install
transitive-yanked-and-unyanked-dependency-a-0abad3b6 --index-url
'https://127.0.0.1:8443/simple-html' --trusted-host '127.0.0.2' -n` also
failed.
## Summary
We now persist the `ResolverInstallerOptions` when writing out a tool
receipt. When upgrading, we grab the saved options, and merge with the
command-line arguments and user-level filesystem settings (CLI > receipt
> filesystem).
## Summary
This PR moves all the CLI code into its own crate, separate from the
`uv` crate. The `uv` crate is iterated on frequently, and the CLI code
comprises a significant portion of it but rarely changes. Removing the
CLI code reduces the `uv` crate size from 1.4MiB to 1.0MiB.
