workspaces: auto-detect Hyprland alongside i3/Sway

Browse Source 
Drive the switcher from Hyprland.workspaces when HYPRLAND_INSTANCE_SIGNATURE
is set, else fall back to I3.workspaces. The ?: model binding only evaluates
the taken branch, so the unused backend singleton is never instantiated (no
stray IPC). Both workspace types share the same shape (name/active/focused/
urgent/monitor.name/activate()), so the chip renderer is unchanged.

// Workspace switcher for a single monitor. Works on both Sway/i3 and Hyprland:
// the compositor is detected once from its instance env var, and the matching
// Quickshell backend model is used. The two backends expose the same item shape
// (name / active / focused / urgent / monitor.name / activate()), so a single
// chip renderer covers both. The `?:` on `model` only evaluates the taken
// branch, so the unused backend singleton is never instantiated (no stray IPC).
