The upgrade of the `radicle-crypto` crate was missed when upgrading
semver versions.
Unfortunately, since it is at the base of the dependency tree, all
crates that depend on it require an additional upgrade.
The trait `radicle_ssh::agent::client::ClientStream` trait was
simplified, because `winpipe::WinStream` is so similar to
`std::os::unix::net::UnixStream` that we can just use the same
implementation for both platforms.
However, obtaining the process identifier of the SSH agent process is
not common on Windows, so we instead track the path that we used to
connect to the agent. This is also helpful on Unix. In some cases, the
path will even contain the process identifier. The path is printed by
`rad self`.
Errors are cleaned up, and error messages are improved.
Directory builder extensions are platform specific and only available on
Unix. Move their use into a conditionally compiled block, so that we can
build on Windows.
`radicle-crypto` is the only crate that actually depends on `ssh-key`. I
overlooked that previously and added it as a workspace dependency. Now I
am limiting its scope again.
