Sharang Parnerkar c293d76e6b refactor(go/ucca): split policy_engine, legal_rag, ai_act, nis2, financial_policy, dsgvo_module
Split 6 oversized files (719–882 LOC each) into focused files under 500 LOC:
- policy_engine.go → types, loader, eval, gen (4 files)
- legal_rag.go     → types, client, http, context, scroll (5 files)
- ai_act_module.go → module, yaml, obligations (3 files)
- nis2_module.go   → module, yaml, obligations + shared obligation_yaml_types.go (3+1 files)
- financial_policy.go → types, engine (2 files)
- dsgvo_module.go  → module, yaml, obligations (3 files)

All in package ucca, zero exported symbol renames, go test ./internal/ucca/... passes.

// NIS2 Module
// ============================================================================
//
// This module implements the NIS2 directive (EU 2022/2555) and the German
// implementation (BSIG-E - BSI-Gesetz Entwurf).
//
// NIS2 applies to:
// - Essential Entities (besonders wichtige Einrichtungen): Large enterprises in Annex I sectors
// - Important Entities (wichtige Einrichtungen): Medium enterprises in Annex I/II sectors
//
// Split into:
// - nis2_module.go — struct, sector maps, classification, derive methods, decision tree
// - nis2_yaml.go — YAML loading and conversion helpers
// - nis2_obligations.go — hardcoded fallback obligations/controls/deadlines
//
// ============================================================================
// NIS2Module implements the RegulationModule interface for NIS2
