🐚 Fix: zsh Pfad-Berechnung mit ${(%):-%x}

KRITISCHER FIX: BASH_SOURCE[0] funktioniert nicht in zsh!

Problem:
- BASH_SOURCE[0] ist bash-spezifisch
- In zsh war SCRIPT_DIR leer → WALDWAECHTER_DIR falsch
- CRUMB_LOGS_DIR: /Users/bmt/Documents/logs (falsch!)
- Sollte: /Users/bmt/Documents/CF_Zero_V1/logs

Lösung:
- if BASH_VERSION → BASH_SOURCE[0]
- elif ZSH_VERSION → ${(%):-%x}
- else → fallback $0

Jetzt funktionieren Pfade in beiden Shells korrekt!

crew_doctor wird jetzt den richtigen Pfad zeigen ✅
