Konsolidierter, bereinigter Stand der Wissensbasis (docs/). Frischer
Wurzel-Commit, um urheberrechtlich problematische Volltexte aus der

- Copyright-Hygiene: 25 Volltext-/Übersetzungsdateien (Sharp 14 Kap.,
  Wala 11 Kap.) entfernt; je Quelle _Fundstellen-Index.md als
  Provenienzbeleg; Quellnachweise + Steuerungsdateien angepasst.
- Konsistenz-Korrekturen: Reichweite 000-013 (Scorecard-Regeln),
  Rule-ID MW-WK-DIFF-101, Quellnachweis-Dateiverweis, Dok.000 v2.0.2.
- Dateinamen-Normalisierung: Startdatei ohne Leerzeichen.
