GEN-4 REW erweitert: alle 3 C-Kombi + pp = REW (Julian bestätigt)

- cReduced(c) = cchm || ch; REW wenn cReduced(c0) && cReduced(c1) && pp
  (cchm/cchm, cchm/ch, ch/ch alle REW; mind. ein volles C = NICHT REW)
- Counterproof-Test: C/cchm + pp und C/ch + pp = nicht REW
- Frozen-Round-Trip-Test: PEW (ch/ch+pp) explizit ausgenommen (intentional
  shadow durch REW-Check per Julian-Regel; PEW bleibt Dropdown-Name)
