Will review more thoroughly later, but one thing I wanted to mention quickly is about go.work. I don't think we want to check that in to the repo? I think that's usually something developers could/would customize locally. I'd actually probably add it to .gitignore...

We should be able to keep it as 0.0.0 in the repo and not need to replace it with the published version.

Got ya. I think you can ignore this until Ci is green. Neet to nurture it down until all parts works ;/

cleaned the root go.mod to be minimal change. All the other child go.mod are just being aligned with root one now.
