Lazy susan: Meta+Alt+Tab spins the panels around you

- ft-screens "spin next|prev|<degrees>": every unpinned screen and
  floating window turns together about a vertical axis through your
  head (0.3 s, eased), so the next panel on the right or left comes to
  straight ahead; the arrangement stays as it is. Taps during a spin
  add to it, from where the panels are headed; grabbing a panel or
  placing it (ft-layout, ft-floatd) takes it out of the spin
- when a spin settles, the panel in front gets the pointer (recenter),
  typing (as after a click), and KWin's active window: its floating
  window, or the top window on a screen (ft-floatd "front N", the KWin
  script's activate-output). KWin's outputs follow the screens'
  new places (ft-layout scale), as after a move
- the input relay: spin_next and spin_prev actions, Meta+Alt+Tab and
  Meta+Alt+Shift+Tab by default; Frametop Input Settings lists them.
  Not Meta+Tab: that's Cmd+Tab on a Mac reached through a remote
  desktop like RustDesk, and the relay would take the Mac's app
  switcher. Meta+Alt+Tab (Cmd+Option+Tab) is unused on macOS,
  Windows, and KDE

Used on the Frame (SteamOS 0.3.0 build 20260922) with one screen and
three or four floating windows, through RustDesk to a Mac.
