feat(wm): add monocle_focus_behaviour to gate monocle cycling

5f629e1f made directional focus cycle the monocle container in the
underlying ring. Useful on a single monitor, but undesired when focusing
across monitors — the focus stays trapped on the monocle workspace
instead of crossing the boundary.

This commit adds a new top-level monocle_focus_behaviour option with two
variants, Cycle (the post-5f629e1f behaviour) and NoOp (the pre-5f629e1f
behaviour, now the default), along with a ToggleMonocleFocusBehaviour
socket message and corresponding komorebic subcommands to flip between
them at runtime.
