Method set_current_view

atomic-repository/src/repository/mod.rs:667–689

Set the current view (internal, does not update working copy). Update the view pointer on disk without materializing. This updates both the in-memory state and persists the change to disk, but does **NOT** update the working copy. The working copy may be left inconsistent with the view pointer — `status()` handles this gracefully (files tracked on other views show as `Added` rather than `Untrac
