Sometimes in my scripts reports are opened with a context manager in case I need to add anything, but then in the context manager I don't change anything. It would be nice if MNE-Python was smart enough in that case not to actually write anything out. This PR adds that! Changes drafted with Claude Opus 5 and reviewed by me.
Wasn't 100% sure if
report.unsaved_changesshould be public or private, but the cost to making it public is low and it seems like it could be useful sometimes. And I figure an explicitonly_if_changed=Truewas a reasonable way to allow people to force a write by passingFalseif they really want to for some reason.
