workspaces: a pill top left on every monitor with its workspaces

- one window per monitor (namespace magic-workspaces, Overlay like the island), showing that monitor's hyprland workspaces in the island's look: cover gradient, pink glow - focused workspace pink, shown-elsewhere soft pink, empty ones dim; hover eases in (one at a time), a click switches workspace - special workspaces are skipped; name-only ones show their first letter - event-driven through Workspaces: redraws only on hyprland events and hover

 - **Background:** a diagonal gradient from the cover's own colours, darkened so white text stays readable.
 - **Opening animation:** the pill fades out, the empty shape grows, then the card fades in. Closing runs backwards. Moving the pointer off the open card closes it.
 - **Every monitor:** each monitor shows the pill. The card opens only on the monitor you click (a keybind opens it on the focused one), and only the focused monitor's pill shows live bars; the others show still bars, which keeps the cost at about one island's.
+- **Workspace pill:** top left on every monitor, that monitor's Hyprland workspaces as round numbered slots in the island's look. The focused workspace is pink, the one shown on another monitor a softer pink, empty ones dim. Click one to switch to it.
