* keybindmgr: avoid uint rollover on mouse keycode
mouse keycode is 0, and the switch case checks for 0 - 8 and rolls over,
just return early if keycode is 0.
* watchdog: avoid data races in watchdog
asan thread sanitizer reported data races in the watchdog from reading
and setting the bool variables make them std::atomic bools. also add a
atomic bool for the main thread to wait for to avoid data race when
reading the config values.
* hyprdebug: change non unicode character to name
asan created false positives and didnt like this bit, so for the sake of
easier debugging rename it to something unicode.
