Implement by-id window addressing in IPC and CLI, fix move-column-to-workspace

This is a JSON-breaking change for the IPC actions that changed from
unit variants to struct variants. Unfortunately, I couldn't find a way
with serde to both preserve a single variant, and make it serialize to
the old value when the new field is None. I don't think anyone is using
these actions from JSON at the moment, so this breaking change is fine.
