feat: calendrier économique TE+Investing, OIS SNB, yields 10Y, taux directeurs corrects
Calendrier économique - Nouvelles sources : TE HTML scraping (483 events/2 sem.) + Investing.com en co-primaires - Dédupe déterministe par clé currency+category+date (±1j pour policy_rate) - Filtre catégorie "other", filtre discours CB (fix doublon TE vs Investing) - CHF/Switzerland via page séparée TE (hors G20) - Fenêtre 14 jours avec ?startDate=&endDate= passés à TE - ForexFactory+FRED en secours uniquement si les deux scrapers tombent à vide Probabilités OIS - rateprobability.com (7 CBs : FED/ECB/BOJ/BOE/BOC/RBA/RBNZ) - investinglive.com (Dellamotta) : scan URL-date 14 jours → couvre SNB/CHF manquant - SNB : 3% probabilité hausse au 19 juin 2026 (source : IL article 2026-05-29) - rate_expectations.json MAJ : RBNZ 79% hike (corrigé depuis 70% no-change stale) - Dédup ±1 jour pour policy_rate (fix doublon SNB TE-18/06 vs IL-19/06) Taux directeurs - USD : scrapeTeRate() = 3.75% (fin midpoint FRED 3.625%) - AUD prev : 4.10% (corrigé depuis 4.60%) - NZD/CHF/JPY/CAD : cohérents avec TE officiel Yields 10Y souverains - Nouvelle lib lib/tebonds.ts : scrape TE bonds, données du jour, cache 1h - Remplace FRED IRLTLT01XXM156N mensuel (JPY/CHF/AUD/NZD avaient 1 mois de retard) - 8 devises + spread vs USD calculé automatiquement - /api/yields et /api/drivers utilisent la même lib Drivers globaux - BTC : ticker/price Binance (plus précis que 24hr lastPrice) - HY Spread cache : 86400s → 3600s (données FRED du jour) - DriversBar : suppression affichage direct US 10Y, tooltip Crb 2-10 affiche US10Y+US2Y Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
