- create linux executables linked statically to musl - drop gnu (glibc) target, executable will work on alpine & glibc based distros (debian etc) - create windows aarch64 target - required update to Cargo.lock to update ring to v0.17 due to build failures on v0.16 - refactor release script & workflow to match pact-reference - builds on pull request to master/main branch, in debug mode - add Docker automated pipeline during release - publish multi-arch amd64/arm64 - publish to DockerHub - publish to GitHub container registry Related epics - musl all the things - pact-foundation/roadmap#30 - publish to github container registry - pact-foundation/roadmap#29

Slim executables
References
Motivation
Some of our client languages necessitate the inclusion of all supported platform/architecture combinations in a single package distributed to end-users.
Reducing the size of the executables and libraries if preferable, if there is no discernible difference for end user.
The proposed set of changes, opts not to set
panic=abortover the default ofpanic=unwind.The inclusion of the
panic=abortwill change behaviour which may lead to changes in how we program (if we are expecting to be able to unwind - maybe more relevant for the ffi?), but leads to smaller binary sizes. To go further than that, we need to build against nightly rust channels, which is probably less than preferable.I believe these set of options provides the best trade-offs whilst remaining on a stable rust channel.
The strip option as a minimum should be included, it is actually now enabled by default in rust 1.77, related issue
