* feat: effective tariff rate source
* fix(trade): extract parse helpers, fix tests, add health monitoring
- Extract htmlToPlainText/toIsoDate/parseBudgetLabEffectiveTariffHtml
to scripts/_trade-parse-utils.mjs so tests can import directly
- Fix toIsoDate to use month-name lookup instead of fragile
new Date(\`\${text} UTC\`) which is not spec-guaranteed
- Replace new Function() test reconstruction with direct ESM import
- Add test fixtures for parser patterns 2 and 3 (previously untested)
- Add tariffTrendsUs to health.js STANDALONE_KEYS + SEED_META
(key trade:tariffs:v1:840:all:10, maxStaleMin 900 = 2.5x the 6h TTL)
* fix(test): update sourceVersion assertion for budgetlab addition
