install: auto-write the floating window rule on Omarchy

Both the Walker entry and the optional clipboard keybind now use the dedicated
'omagrab' app-id, and the installer writes the float/center/size rule to
windows.conf (idempotent, backed up, reloads Hyprland). No manual window-rule
step left — only the optional keybind is printed.

 a floating window with the URL already filled in.

+The installer already added the floating window rule (`omagrab` floats small and
+centered however it's launched), so all you need is the keybind. Add to
+`~/.config/hypr/bindings.conf`:
 
 ```ini
 bindd = SUPER SHIFT, V, omagrab, exec, xdg-terminal-exec --app-id=omagrab -e omagrab --clip
 ```
 
-And a floating rule in `~/.config/hypr/windows.conf` (Hyprland ≥ 0.55 syntax):

-windowrule = float on,     match:class ^(omagrab)$
-windowrule = center on,    match:class ^(omagrab)$
-windowrule = size 520 260, match:class ^(omagrab)$

 Reload Hyprland (`hyprctl reload`). Now: **copy a link → `SUPER+SHIFT+V` →
 omagrab floats with the URL ready → `Tab` to pick mode → `Enter`.**
