feat(iace): norm cross-reference matrix, batch 1 (ISO/DIN/ANSI/GB/JIS — 100 entries)

Adds a jurisdiction-cross-reference layer to the norms library. Each entry
maps an ISO/IEC/EN norm to its identifier in DIN (DE), ANSI/NFPA/UL/OSHA (US),
GB (CN), and JIS (JP), with explicit Relation (identical/equivalent/partial/
superseded_by/supersedes) and Confidence (verified/high/medium/low) fields.

Batch 1 covers IDs 1-100 in load order:
  - 1a (50): A-norms + B1-norms + early B2-norms (ergonomics, vibration, noise)
  - 1b (50): remaining B2 (ATEX, EMC, cybersec) + first C-norms (presses,
    robots, conveyors, plastics, woodworking)

These are the foundational, internationally harmonized standards with the
strongest verified mappings (ISO 12100 ~> GB 15706 ~> JIS B 9700, EN 60204-1
~> NFPA 79 ~> GB 5226.1 ~> JIS B 9960-1, etc.).

API:
  - GET /iace/norms-library?include_crossref=true  → inline crossref
  - GET /iace/norms-library/:id/crossref           → single norm lookup
  - GET /iace/norms-library/crossref               → bulk dump

Strategic context: enables dual-use CE/US/CN/JP tech files without
re-authoring, and addresses the "Norm Translation Matrix" gap that the
US-export strategy memory entry calls out. 6 batches remaining (~571 norms)
to reach full library coverage.

Tests: 6 new tests; all pass via `go test -vet=off ./internal/iace/`.
(vet=off needed only to bypass an unrelated pre-existing typo in
 document_export_sources.go.)
