v0.2.2

Fixed

• The hook no longer runs on files whose name merely ends in just, such as robust or adjust.txt. It matches
  justfile, .justfile, Justfile (any case of the first letter) and *.just.
• A file just cannot parse now prints the just error instead of failing silently.

Changed

• The script starts with #!/usr/bin/env bash (it was #!/bin/bash), for systems without /bin/bash such as NixOS.
• Tests (tests/test.sh: direct run, spaces in paths, modules, syntax errors, missing just, prek try-repo) run in
  CI on Linux and macOS (bash 3.2).
