Markenwissen-Wissensbasis: Konsistenz-Korrekturen + Copyright-Hygiene

Konsolidierter, bereinigter Stand der Wissensbasis (docs/). Frischer
Wurzel-Commit, um urheberrechtlich problematische Volltexte aus der
Historie zu entfernen (die bisherige Historie bestand aus einem einzigen
Initial-Commit).

Enthaltene Änderungen (vgl. docs/_Steuerung/CHANGELOG.md, 2026-05-29):
- 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.

Originale (Wala/Sharp E-Books) privat außerhalb des Repos archiviert.
