A right-aligned v{CFBundleShortVersionString} label fills the unused
header space next to the CCS name, styled like the subtitle and hidden
when no bundle version is available (e.g. swift run). The display
logic lives in CCSBarCore as a pure helper with ccs-bar-check
coverage, making the on-screen build identifiable after reinstalls.
