Merge feature/gen-4c (GEN-4c): PEW→REW konsolidiert (Julian REW-1) + REW-2 A-unabhängig verifiziert + aa-Test

- catalog.ts: 'Pink Eyed White (PEW)' -> 'REW' (frozen rename; chch+pp
  engine-computes 'REW' per Julian; entry now round-trips correctly)
- genetics.test.ts: REW_SHADOWED-Ausnahme entfernt (kein Bedarf mehr);
  CATALOG[0]-Assertion auf 'REW'; aa cchmcchm+pp-Test als REW-2-Nachweis
  (Julian: A-Locus egal fuer REW-Bedingung)
- chipColors.ts: 'REW'-Chip ergaenzt (gleiche Farbe wie PEW; additive;
  PEW-Eintrag bleibt fuer Rueckwaertskompatibilitaet waehrend DB-Migration)
- Seed-Artefakte regeneriert (70 Reihen, REW statt PEW an Position 0)
- FLAGGED to god: 'Altweiss (REW)' hat volles C (C:'C') -> faellt NICHT
  unter REW-Bedingung; warte auf Julian-Entscheid vor Aenderung
