fix workspace clicks and the island stuck after a hidden start

- workspace pill: clicks did nothing. amane's Workspaces::focus sends
  'dispatch workspace N', which hyprland 0.56 with a lua config turns into
  hl.dispatch(workspace N) and rejects. dispatch the lua form the user's
  keybinds use, hl.dsp.focus({ workspace = N }), through hyprctl on its own
  thread (named workspaces with negative ids are left out)
- island: 'magic-island has no child to draw' at startup without a player,
  and the island then never appeared. hyprland 0.56 configures a layer
  surface before its first commit (seen with WAYLAND_DEBUG), so a window
  that starts visible(false) gets a size, amane runs the empty view, logs,
  and waits for frame callbacks an undrawn surface never gets. with no
  player the island is now an empty click-through window instead
- verified on the desktop: 0 'no child' lines, island draws at startup and
  shows on all 4 monitors when a player starts
