Make it possible to fully release problems in a standalone service that vendors can work on self-serve.

I thought this would require a lot of work but after I did this work e2ee3d7

I think we can just tell a vendor to git clone reference kernels, popcorn-cli and kernelbot, make the changes they need to and let claude validate that everything is working well

So there's still some work left but not a lot
