Add support for Vernier profiler

[MikeMcQuaid]

Needs Ruby >=3.2 so blocked on that.

How slow/fast is this meant to be? I've been staring at this for the past 5 minutes or so:

I haven't gotten this to work, but it doesn't seem to break anything, so fine with me.

@carlocab Thanks! Let's merge and iterate. Hopefully can help you debug this 🔜

I've been staring at this for the past 5 minutes or so:

I saw it hang a few times, unsure why. It worked if I Ctrl-Cd and tried again.

Probably worth us figuring this out as it's way better than ruby-prof etc.

Did this several times and didn't get anywhere, sadly.
