the location of files is hard-coded by mdBook.
there is also seems to be no way to define custom templates, therefore
all styling has to be done in the CSS override.

This PR reduces the creation of short-lived basic_json objects while
parsing flake.lock files. For large flake.lock files (~1.5MB) I was
observing ~60s being spent for trivial nix build operations while
after this change it is now taking ~1.6s.

the crash when calling `nix help-stores` was probably introduced an
artifact from a prior untangling of merge conflicts.
that said, `nix help-stores` should eventually cease to exist in favor
of dedicated `--help` outputs and `man` pages for the various store
types.
It is possible to exfiltrate a file descriptor out of the build sandbox
of FODs, and use it to modify the store path after it has been
registered.
To avoid that issue, don't register the output of the build, but a copy
of it (that will be free of any leaked file descriptor).
This makes something in Hydra bit simpler. If someday the default
depends on the other config options, we can always change it back.

Instead of
error: unexpected end-of-file
you now get
error: Nix daemon disconnected unexpectedly (maybe it crashed?)

In rare cases (e.g. when using allowSubstitutes = false), it's
possible that we simultaneously have a DerivationGoal *and* a
SubstitutionGoal building the same path. So if a DerivationGoal
already built the path while the SubstitutionGoal was waiting for a
download slot, it saves us a superfluous download to exit early.

In the "discard" case (i.e. when the store path already exists
locally), when we call parseDump() from a Finally and it throws an
exception (e.g. if the download of the NAR fails), Nix crashes:
terminate called after throwing an instance of 'nix::SubstituteGone'
what(): error: file 'nar/06br3254rx4gz4cvjzxlv028jrx80zg5i4jr62vjmn416dqihgr7.nar.xz' does not exist in binary cache 'http://localhost'

Previously, IFDs would be built within the eval store, even though one
is typically using `--eval-store` precisely to *avoid* local builds.
Because the resulting Nix expression must be copied back to the eval
store in order to be imported, this requires the eval store to trust
the build store's signatures.

this part must have been moved quite a while ago, but apparently so far
no one noticed

Shouldn't hurt to do this. In particular, this should speed up
shutting down the PathSubstitutionGoal thread if it's copying from a
remote store.
