feat: status bar visual upgrade, unified release job

Status bar: top hairline separator, vertical divider between toggle
and status text, segmented-control container with border/separators
around view buttons, accent line 2->3px, proper sizeHint with
breathing room, default system font instead of monospace override.

CI: replace per-job release uploads with a single release job that
waits for both windows and linux, then publishes both artifacts to
one GitHub release.
