We don’t use them (yet?) in the Platform, and working definitions are
always available in `blockfrost-ops`, who _do_ use them.

the blockperf-install.sh script can also be started and used directly afterwards.

## Summary

`scripts/ci/run-fourmolu.sh` builds a path regex from `$(pwd)` and
passes it to `fd --full-path`. `fd` matches that regex against the
**canonicalized** path (symlinks resolved), while `$(pwd)` returns the
**logical** path. When the script is invoked through a symlink (e.g. a
convenience symlink pointing to the real checkout), the regex is built
from the symlinked name but `fd` is walking the resolved path, so the
regex matches zero files. The script then exits cleanly without
formatting anything, which caused the nix fourmolu check to fail on CI
while local runs reported "no changes" — a silent and confusing failure
mode.

Switching to `pwd -P` emits the physical path, so the regex and the
paths `fd` actually walks are in the same namespace.

`scripts/ci/run-cabal-gild.sh` on `main` does not use this pattern, so
it needs no change.
