hypr: make Super+Alt+C toggle a runtime-selectable AI scratchpad

Super+Alt+C now toggles whichever AI app is currently selected (Codex or
Claude Desktop) instead of always Codex. The selection is read from
$XDG_STATE_HOME/hypr/ai-scratchpad at keypress time, so switching is
dynamic and needs no Hyprland reload.

Hyper+C opens a rofi chooser (rofi_ai_scratchpad.sh) to pick between the
two, replacing the old "Open Codex session menu" binding. It writes the
choice and brings the selected scratchpad into view.
