just some minor ubsan finds, keycodeToModifier was called with a 0 keycode on mouse keys, and the switch case rolled it over on 0 - 8, no harm but unnecessery.
the watchdog is a seperate thread and hit data races in both reading the config values and reading the bools with the main thread, add a atomic bool for the main thread to wait until the watchdog has read its configvalues so it doesnt hit races in reading the config values with main thread. and change the members to atomic aswell.
also with enabling various ubsan/threadsanitizer/asan flags it gave a few false positives from the non unicode characters in hyprdebug, just change them to a unicode name.
