Was hoping to leave this enabled for a little while as core community
members test this script out, but Apple's aggressive release timeline
for macOS 15 Sequoia has caught us off-guard here.
It's probably not ideal for a general audience if the script spews all
of this output--and people can still force bash to run in trace mode
if we really need to debug a problem.

When `nix fmt` is called without an argument, Nix appends the "." argument before calling the formatter. The comment in the code is:
> Format the current flake out of the box
This also happens when formatting sub-folders.
This means that the formatter is now unable to distinguish, as an interface, whether the "." argument is coming from the flake or the user's intent to format the current folder. This decision should be up to the formatter.
Treefmt, for example, will automatically look up the project's root and format all the files. This is the desired behaviour. But because the "." argument is passed, it cannot function as expected.
As a hacker, I should be able to checkout the repo, and find relevant
information on how to develop in the project somewhere in the top-level.
Either in the README.md, or CONTRIBUTING.md or HACKING.md files.
This PR symlinks the HACKING.md into the right place in the manual.
On macOS, `mkdir("x/')` behaves differently than `mkdir("x")` if `x` is
a dangling symlink (the formed succeed while the latter fails). So make
sure we always strip the trailing slash.

This fixes the warning

When we're fetching by rev, that file doesn't necessarily exist, and we
don't care about it anyway.
The current backport action cannot automerge because
the github action bot does not trigger github CI actions.
Mergify instead does not have this limitation and can also
use a merge queue.
On top we have now a declarative configuration to allow
contributers to add new tests to required without having access
to the github org.
An example pull request and backport can be seen here:
https://github.com/Mic92/nix-1/pull/4
and here:
https://github.com/Mic92/nix-1/pull/5
To complete the setup the mergify app must be enabled for this repository.
It's already installed in the nixos organization for nixos-hardware and
other repositories.

Fixes
$ nix flake metadata --store /tmp/nix nixpkgs
error: path '/tmp/nix/nix/store/65xpqkz92d9j7k5ric4z8lzhiigxsfbg-source/flake.nix' is not in the Nix store
This has been broken since 598deb2b23.
downloadTarball() is used by `-I foo=<url>` etc. fetchToStore() needs
the accessor to have a fingerprint to enable caching.
Fixes#11271.
