0.6.0

There's a lot of internal cleanups, CI enhancements, and smaller bugfixes in this release. For example, this release fixes compatibility with "long" symlinks. On the internals side, we are starting an effort to switch to rustix and cap-std.

There's a semver bump because of a few small tweaks; one of them is that we now depend on a new major version of containers-image-proxy which has a Config struct with different types.

We now have a build-time feature proxy_v0_2_3 - enable this if you can hard depend on skopeo v1.5.2.

Thanks to all contributors!
