data(brand): backfill verified flag on bulk-seeded brands

[Seungpyo1007]

Summary

Backfill the verified field on the 129 brand records that were missing it (bulk/auto-seeded brands), setting verified: false to match the bulk-import policy. All 189 brands now carry the field, closing the "brand category missing verified metadata" gap tracked in #1.

Changes

• 129 data/brand/**/*.json records get verified: false (inserted before source_urls, matching the 60 brands that already had the flag).
• No new records; no existing values changed beyond adding the field.
• Public dump unaffected — the brand serializer does not expose verified, so site/public/v1 is byte-identical (no dump refresh needed).

Verification

• python -m app.validate PASS
• python TechEngine/integrity_check.py data --strict PASS
• git diff --check origin/main...HEAD PASS
• No site/ or site/public changes → site build N/A

Closes #1

Warning

Tracked verified coverage is below 50% for brand 0.0% (0/189), tablet 0.0% (0/3048), watch 0.0% (0/378), pda 0.0% (0/110), gpu 0.0% (0/2030), smartphone 0.2% (184/90118), all 1.2% (1218/101954), soc 2.8% (58/2104), and 1 more.
Tracked coverage excludes records missing the verified field; see the Missing verified column for those records.
This does not fail validation. Keep imported records verified: false until manual audit, but treat this as follow-up verification work before relying on the affected categories as curated data.

Validation notes

• Full advisory outlier listings are suppressed on successful runs because they are dataset-wide and mostly stable between PRs.
• Failure runs still include a detailed log excerpt for debugging.
