feat: Watch and reload config.py type file for changes about xkeysnail HOT 3 OPEN

I am using inotifywait in a bash script that restarts the xkeysnail service atm as a workaround, but it is a poor workaround that can result in stuck keys actually. May highlight an issue though, it'd be good to have xkeysnail release any potential keys or modifiers on startup, although xkeysnail has no systemd component natively.

Interesting, I'd have assumed that when we die the virtual keyboard we created goes away and all it's keys with it... if keys are really being persisted across restarts I think you'd want to lift them both on shutdown AND startup.

I'm not sure if you can even query uinput for "which keys are currently down" though...

What type of glitches are you seeing exactly from stuck keys? Because once we're gone we aren't sending any more REPEAT events... so the only thing that might be persisted is the actual "PRESS" state inside uinput itself... I guess that could be enough to mess up modifiers... though really it's probably the user facing software persisting this state, not uinput itself... (which makes more sense)

In any case this should be fixed just by doing proper cleanup when asked to terminate... basically ask output to release all keys.

Something like watching for SIG_TERM and doing proper cleanup:

Note I'm still not 100% clear on which signals are sent when, but this is the right approach me thinks.
