exit-hook

Hello! Thanks for your awesome projects. They provide really good workarounds for current JS ecosystem strange problems. I've faced an issue with flushing the stdout/stderr buffers before the exit. Seems to be that is the root problem. Some hacks like in https://github.com/cowboy/node-exit/blob/master/lib/exit.js is still required in modern node (v20.4.0). My proposal is to integrate the solution in exit-hook, as it's not possible to use these modules together.

We would like to write all debug messages from to our own Kibana with some field predefined. Currently, uses to write any logs. Could you please introduce ability to intercept log messages or override the logger at all?

After updating to 5.0.0, it seems exit codes are not being passed through anymore. Downgrading to v4 fixed the issue for me. https://stackblitz.com/edit/stackblitz-starters-xwbihfsk
