CI was failing due to
5.2.0+trunk
but is otherwise green.
I've added fixes for these in f75289c and 4fda9c2
This should fix #359 - a source of occasional false alarms.

In comparison, this PR's macOS-ARM64 5.2.0~beta2
and trunk workflows triggered one after 17 and 122 attempts, respectively.
Out of 38 workflows 3 failed with 1 genuine issue and 2 borderline false alarms / CI issues.
In an attempt to trigger an error on the in-house silicon too, adff14c bumps the count to 2500 as already done in #304.
As this is a negative test, this should only matter to macOS ARM64 on multicoretests-ci
that have been hitting the 1000 count. I can however see that this does not make a difference :shrug:
Reminding myself of the macOS OCurrent setup from https://tarides.com/blog/2023-08-02-obuilder-on-macos/ I suspect the test is witnessing the difference between ZFS vs whatever the GitHub actions runners are using underneath. Ideally the test suite should hold up against changes of the underlying file system. However
As such, collecting the macOS runners under the same CI system seems reasonable.

The latter two failures will disappear with the merge and deployment of https://github.com/ocurrent/multicoretests-ci/pull/36
Out of 38 workflows 3 failed with 1 genuine issue and 2 borderline false alarms / CI issues.
Merging this one as ocurrent/multicoretests-ci#36 has now been merged

None of the 37 workflows failed :tada:
For quite some time, GitHub actions only supported macOS on Intel hardware. That has changed recently: https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners/about-github-hosted-runners#supported-runners-and-hardware-resources
Interestingly, we have used
macos-latest
which then changed hardware underneath our feet. I noticed, because the once-per-week 5.0.0 and 5.1.1 workflows started finding anSTM
Sys
parallel counterexample relatively consistently. (details below)This PR thus adds explicit macOS Intel (macos-13) and ARM64 (macos-14) workflows, thus collecting them both in the same GitHub actions CI "backend". I'll write a separate PR to remove the macOS ARM64 runners from multicoretests-ci.
