New `local.hyprland.workspaceRules` option binds workspaces to monitor
connectors so each has a home screen; a consumer sets it from its own host
config (empty by default). Soft binding — an absent monitor's workspaces fall
back to an active one, so a laptop-only session still works.
`$mod+o` / `$mod SHIFT+o` focus and move the current workspace to the other
monitor. When rules are set, an `exec-once` nudges a single-monitor session to
workspace 1 rather than a support monitor's high default.
