Gulum 8dfad32918 SEED-HELL v2: 5 CP-*-Hell ans Ende haengen (IDs 62-66, kein ID-Name-Drift)
Erster Ansatz (Rename-in-Place-Shift) wuerde 17 Hand-zugewiesene
Gerbil.ColorVarietyId-FKs still verfaelschen (1 Tier auf CP-Fuchs live
bestaetigt). Stattdessen: 5 neue Eintraege ans ENDE gehaengt (IDs 62-66),
die 61 bestehenden Eintraege unveraendert.

Migration ReseedColorVarietiesGen3g: NUR 5 InsertData (IDs 62-66),
kein UpdateData, kein DeleteData, keine FK-Drift moeglich.

Neuer Test SeedGen3g_existing_varieties_preserve_id_name_binding:
asserts CP-Fuchs (ID 58) bleibt CP-Fuchs, alle 5 neuen IDs 62-66
haben korrekte Namen, Gesamtzahl = 66.

Gate: 127/127 C#-Tests, has-pending-model-changes = No.
