precompilepkgs: make the circular dep warning clearer and more informative

[IanButterworth]

Was e.g.

┌ Warning: Circular dependency detected. Precompilation will be skipped for:

Now

Thanks to @topolarity figuring out proper cycles tracking.

[topolarity]

We should probably backport to 1.10 too, since we expect that users will be hitting extension cycles a lot more often on that release.

In 1.11 these cycles are supposed to be impossible, except for environment tearing (where you end up with a package graph that doesn't actually ] resolve) and any implementation bugs (some of which were not fixed until.. yesterday 😉)

Still very good to have (esp. on 1.10), just want to be clear about whether this is a "normal" error any more

[topolarity]

Looking great! I think it's much clearer to users what's going on here now.

Thanks for iterating on this @IanButterworth

[topolarity]

Oh the cycle order does look a bit "backwards" to me

I would have expected the dependency of a package to be above it, not below

I would have expected the dependency of a package to be above it, not below

I think of it the other way. Matching the sentence order for "Foo depends on Bar, which depends on Baz"

Foo
 Bar
  Baz

[topolarity]

Hmm.. What if we reverse the indentation from greatest to smallest?

  Baz
 Bar
Foo

Does that align our intuitions?

[topolarity]

I still find the staircase weird here (and my first instinct is to read it "backwards"), but this is a big improvement and all the functionality looks ship-shape to me

Good to merge, I think!

[IanButterworth]

Yeah, lets see what people make of it and tweak if there's concensus
