Hand the terminal launcher the focused window's pid from Lua (#13521)

To open a new terminal in the focused terminal's directory, the launcher
asked Hyprland for the active window with hyprctl, ~10ms on every
SUPER+RETURN. The binding now reads the pid from hl.get_active_window() and
passes it as --pid. Without one, from the menu or a shell, the launcher asks
Hyprland as before.

The bind is now a Lua function, which Hyprland reports only as __lua, so
o.bind_commands records the command it stands for and the keybindings menu
still launches a terminal when the entry is picked.
