* 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.
* watchdog: dont detach and cause race condition
instead of detaching and causing a race condition on destruction where
the thread is alive and watchdog has been destroyed, check if its
joinable and join it on destruction.
causes heap use after free on exit of compositor.
* render: add checks for compositor shutting down
avoid member call on null pointer, if the g_pHyprRenderer is destroyed
we can call the member makeEGLCurrent on it, causes undefined behaviour
on destruction of the compositor/hyprrenderer.
