Float key in the input relay, docking everything, and the plan for profiles

The input relay owns the float key now: float_toggle (Meta+Shift+F unless the
rules have their own key combinations) floats the window under the pointer, or
the active one over the wallpaper, and docks it if it floats. dock_all puts
every floating window back. Both are mappable to mouse and controller buttons,
and work without pointer mode. The KWin script no longer registers a shortcut,
and ft-floatd drops the old one. Key combinations move to Input Settings'
Keyboard page.

docs/floating-windows.md records the decisions from 2026-09-30 (the title bar
button, Launch as Standalone, profiles), and docs/profiles.md plans profiles.
