June 1st is getting really close. *In less than two weeks we won't have
a working CI anymore*. Effectively that's probably one week of calendar
dev time that's left, because almost everyone is at PGConf.dev right
now.

So today I decided to take a stab at an initial GitHub Actions yaml
file, as that seemed like the only viable option within that timeline.
Note: Claude Code wrote this file entirely, following extensive
back-and-forth with me after repeatadly getting red builds due to some
differences between Cirrus and Github Actions.

But finally, I managed to get a green build for all systems that we
support on Cirrus CI!

IMPORTANT CONTEXT: I only did a cursory review of the workflow file that
Claude created. So there's probably still a bunch of cleanup to do, but
I at least wanted to share this initial base. I don't know if I'll have
any more time to work on this before June 1st. I have a newborn that's
taking up a lot of my spare time. So, I'd be very happy if someone else
wants to take this patch over and get it to a committable state.

A few things (apart from more extensive review) that I think should be
improved soon (but maybe not before the first commit):
1. io_uring support is disabled. I couldn't get it to work on the GitHub
   Actions runners, I think it's disabled in the host kernel. @Andres
2. It's not using pre-built images at the moment, except for the Linux
   docker images I think. So it re-downloads a bunch of dependencies for
   every build for most OSes. @Bilal or @Andres
3. There's currently no integration with the CFBot or commitfest yet. @Thomas

P.S. This is not an attempt to decide on the proprietary vs self-hosted
opensource discussion. Self hosting might still be the best long-term
solution. I just don't realistically see that happening within two
weeks.
