Big research drop across the regulatory docs. Added H5N1 federal order, VFD, NIST/NAWI scales, Windsor Framework, revFADP, eIDAS, and a clutch of new EU jurisdictions (IT, ES, DK, BE) to the cross-market plan. The data model grew accordingly: first-class Veterinarian, Transporter, Vehicle, Scale, WeighingRecord, HoldingHealthStatus, MedicationRecord, VfdOrder, AnimalGroupBatch for pig/sheep batches, and a partial-unique-index note on AnimalIdentifier so tag replacements stop fighting the schema. No code yet, just the map of the territory getting honest about how big the territory is.
