The toolbar layout on macOS now lists Play, Download, Share, Add to Playlist
and Bookmark as separate toolbar items, with a spacer setting Play apart from
the secondary actions. The primary action picker stays iOS-only, where the
pinned action plus the ⋯ menu layout is kept, and macOS gets its own settings
footer text.
The macOS items are written out explicitly rather than with ForEach: a ForEach
inside the toolbar builder is evaluated once and never re-renders on state
changes, which left the bookmark and download icons stale.
