* feat: add pytest unit tests and CI workflow Add 67 tests covering both create_listing.py and dedup.py with shared Pillow-based image fixtures. Add GitHub Actions workflow to run tests on Python file changes. * fix: address PR review feedback - Use monkeypatch.chdir(tmp_path) so tests write to temp dirs instead of polluting the repo's README.md and index.html - Strengthen unicode filename test to assert URL-encoded form (%C3%A9) - Move hashlib import to module level in test_dedup.py - Remove unused _zero_hash helper and Path import - Prefix unused tuple unpacking variables with underscore * fix: add docstrings and strengthen degenerate hash test - Add docstrings to all test classes, methods, and helper functions to achieve 100% docstring coverage - Strengthen test_skips_degenerate_hashes to assert groups == [] instead of only checking for no-crash * fix: use hardcoded MD5 digests and add fixture validation - Replace hashlib.md5() calls with known digest constants to remove hashlib import from test module - Add input validation to _make_gif fixture for clear error messages on empty colors or mismatched durations length
