@grahamgower -- not sure I did the right thing re: mergify?

[grahamgower]

There should be mergify lines for each of actions that need to pass for merging to be allowed. For the test scenarios, that looks right. But the new dev deps lines don't seem right, because the python version in the dev.yaml/dev-deps job is for python 3.12 only. Alternately, you could add python 3.14 to the dev-deps. It's all a bit of a pain to keep updated...

[molpopgen]

I've removed the checks on dev-deps.

I agree that this is a lot to keep track of. I stopped using many of these tools in other projects for that reason.

LGTM.
