- #1: check_preflight() prüft beim Start tesseract + gs, wirft PreflightError. CLI endet mit Exit 2 statt grün zu bleiben. - #2: run_once() gibt Anzahl fehlgeschlagener PDFs zurück, CLI endet mit Exit 1 wenn mindestens eine Datei scheiterte. - pytest-Suite mit 11 Tests für beide Szenarien - ocrmypdf-Import lazy in processor.py (Tests ohne ocrmypdf möglich) Closes #1, #2 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
