Seems to fix or at least make a pretty bad memory leak much slower.
I hate ws but the only other library is written by someone who isn't
a very nice person (putting it on the nice side)
We publish them now, so let's use them in cvmts!
Additionally, this removes the 'shared' module entirely, since it has little purpose anymore. The logger is replaced with pino (because superqemu uses pino for logging itself).
doesn't really need to be two seperate libraries. also preperation for other funnies
the build script has been replaced with a much saner justfile which uses much saner "yarn workspace" invocations instead of blindly cding all over the place
