bug: hyprland.lua Super+M exit fallback uses invalid hyprctl dispatch syntax

[stanfish06]

Same class of bug as #63 (DPMS dispatch). The Super+M keybind in hyprland/hyprland.lua has a broken fallback:

hl.bind(mainMod .. " + M", hl.dsp.exec_cmd("command -v hyprshutdown >/dev/null 2>&1 && hyprshutdown || hyprctl dispatch 'hl.dsp.exit()'"))

hl.dsp.exit() is a Hyprland Lua API call — it only works inside hyprland.lua's runtime. Passing it as a string argument to hyprctl dispatch silently does nothing. If hyprshutdown is not installed, Super+M will fail to exit Hyprland.

The correct hyprctl dispatch keyword for exiting is just exit:

-hl.bind(mainMod .. " + M", hl.dsp.exec_cmd("command -v hyprshutdown >/dev/null 2>&1 && hyprshutdown || hyprctl dispatch 'hl.dsp.exit()'"))
+hl.bind(mainMod .. " + M", hl.dsp.exec_cmd("command -v hyprshutdown >/dev/null 2>&1 && hyprshutdown || hyprctl dispatch exit"))

Fix is in the open PR.
