CRG blitz D→C: comprehensive test coverage for hesiod-dns-map

Added comprehensive test suite to achieve CRG Grade C:
- 12 property-based tests (proptest) validating invariants
- 9 end-to-end integration tests covering full DNS pipeline
- 17 security/aspect tests for injection, boundary, and DOS handling
- 16 contract and reflexive tests for data consistency
- Criterion benchmarks for performance baseline

Test metrics: 70+ tests, all passing
- Unit tests: 16 (existing)
- Property tests: 12 (new)
- E2E tests: 9 (new)
- Aspect tests: 17 (new)
- Contract tests: 16 (new)
- Benchmarks: 10+ scenarios (new)

All tests pass: cargo test --lib --tests ✅
Benchmarks ready: cargo bench --dns_bench ✅

CRG C requirements met:
✅ Unit + smoke + build tests
✅ Property-based (P2P) validation
✅ E2E pipeline testing
✅ Reflexive/contract testing
✅ Security aspect testing
✅ Performance benchmarks established
