Description

In working through the new cross-realm spec in code. I find myself having to dig into which realm I'm hanging out in across various functions. I'd love a way to use a "probe" to give me the "realm stack" at some point in the code.

Imagine something like:

realm.Probe("my annotation")

// Probe Annotation: my annotaiton
// Realm Layer         Address        pkgPath
//   0 (current)        g1...           gno.land/r/foo
//   1                  g1...           gno.land/r/bar
//   2 (origin)         g1...                           

Maybe have the ability to use an IO Writer or some other way to redirect so it can be gathered, or fed into a structured logging. But for debuggin purposes, this would be really nice to have a "one liner" where I throw in an annotation and it outputs my annotation at that point in the code + the Realm Layers so that I understand what realm context I'm in at that point.
