* doc: fix `directory` definition in nix-archive.md
Before the change the document implied that directory of a single entry
contained entry:
"type" "directory" "type" directory" "entry" ...
After the change document should expand into:
"type" "directory" "entry" ...

The code that counts the number of elided attrs incorrectly used the
per-printer "global" attribute counter instead of a counter that
was relevant only to the current attribute set.
This bug flew under the radar because often the attribute sets aren't
nested, not big enough, or we wouldn't pay attention to the numbers.
I've noticed the issue because the difference underflowed.
Although this behavior is tested by the functional test
lang/eval-fail-bad-string-interpolation-4.nix, the underflow slipped
through review. A simpler reproducer would be as follows, but I
haven't added it to the test suite to keep it simple and marginally
faster.
```
$ nix run nix/2.23.1 -- eval --expr '"" + (let v = { a = { a = 1; b = 2; c = 1; d = 1; e = 1; f = 1; g = 1; h = 1; }; b = { a = 1; b = 1; c = 1; }; }; in builtins.deepSeq v v)'

Make it easier to find the documentation, and the example might be enough for most cases.

We don't apply any patches to it, and vendoring it locks users into
bugs (it hasn't been updated since its introduction in late 2021).

On one hand, new things should be formatted. On the other, we just
bacported this file to many prior branches, and if we need to make
changes to it and backport them also, formatting the file on master but
not the release branches would cause issues.
We're building a bit of Darwin meson indirectly through `checks`,
but it'd be annoying to encounter broken un-`check`-ed stuff
during the porting process, so let's just do the right thing now.
This avoids polluting nixComponents with things that aren't our
components.
Fixes the extraction of passthru tests, which failed for boehmgc
which had many irrelevant ones anyway.
flatMapAttrs is easier to read because it introduces the values
before using them, kind of like a `let` bindings with multiple
values.
The repeated comments remind the reader of the purpose of the
innermost attrsets, which is actually very simple.
Knowing that they go right into the result should help a lot
with building a mental model for this pattern.
It was added above this conditional
Worker::Worker(LocalStore & store)
: store(store)
{
/* Debugging: prevent recursive workers. */
if (working) abort();
working = true;
However, `working` has since been removed.
