"""A test rule that compares two binary files or two directories.

Similar to `bazel-skylib`'s [`diff_test`](https://github.com/bazelbuild/bazel-skylib/blob/main/rules/diff_test.bzl)
but also supports comparing directories.

The rule uses a Bash command (diff) on Linux/macOS/non-Windows, and a cmd.exe
command (fc.exe) on Windows (no Bash is required).
