I was playing around with the rule avoid-global-state While I don't think we should enable it, because we do have several totally legitimate cases of what the rule considers global state, it did help me find any current cases where the things just should be final constants. So this PR will mark semantically final variables as final (or const) proper, exclusively on examples (no violations on actual src code are legit).
