just: exclude .direnv from shfmt/taplo/nixfmt/justfile lints

The check/ci/fix recipes globbed the whole tree, so direnv's nix cache
(.direnv/, gitignored) tripped shfmt and taplo on generated direnv scripts
and crane's vendored test-fixture TOMLs. Real GitHub Actions CI has no
.direnv directory, so this only bit local `just ci`. Exclude it via the
find `-not -path` lists (nixfmt + justfile), a `grep -v` filter on
`shfmt -f` output, and the `.taplo.toml` exclude list.
