Chore: Default path_prefix to the repository root

Every sibling action in this organisation declares path_prefix with a . default — 28 of them. This one omitted it, so the declared interface didn't state where the action looks by default, and callers had to infer it or read the implementation.

Behaviour is unchanged

The action already normalises an empty value to . internally:

path_prefix="$PATH_PREFIX"
if [ -z "$path_prefix" ]; then
  path_prefix="."
fi

So this makes the declared interface match what the implementation always did. The practical gain is that GitHub surfaces the default in the Actions UI and in generated documentation, rather than leaving it blank.

Context

Part of a small consistency sweep across the estate, alongside gradle-build-action#103, which aligns that action's outlier path input onto path_prefix.

Deliberately not included in the sweep: python-audit-action, which defaults path_prefix to ''. That empty default is load-bearing — it is passed to pypa/gh-action-pip-audit as inputs:, where empty means "audit the installed environment" while '.' would mean "scan this directory". Changing it there would alter what gets audited.

Validation

pre-commit run --all-files — all hooks pass.

Pull request overview

Aligns this action’s declared path_prefix input interface with its existing runtime behavior by surfacing the repository-root default in action.yaml, improving consistency with sibling actions and making the default visible in the GitHub Actions UI/docs.

Changes:

• Set inputs.path_prefix.default to '.' in action.yaml to explicitly document the already-implemented default behavior.
