Humm... what if I prefer having 2 separate files ? This is so much easier to read, especially when each script grow... (not the case here, I agree).

Also, on branches, I find it better to run only on pull_request (not on push) to save some executions.

Ok, I have merged the 2 workflows in a single file. I have tried to optimise the code but you cannot get rid of the actions/checkout@v4, actions/setup-node@v4 and npm ci steps.
