feat: MVP Fase 0 — Process Cost Platform v0.1.0
Plataforma completa de análisis de costos operativos basada en BPMN 2.0. Funcionalidades incluidas: - Import de archivos BPMN 2.0 por drag & drop + 3 procesos de ejemplo - Visualización read-only del diagrama (bpmn-js) - Configuración de actividades (costo, tiempo, recursos asignados) - CRUD de recursos (rol, persona, sistema, equipo, insumo) - Configuración global (moneda, overhead %, nombre, cliente) - Motor de simulación determinístico agregado con propagación de gateways XOR/AND - Reporte visual con mapa de calor en dos modos (relativo/absoluto) - Gráficos: KPIs, top actividades, composición, costo por recurso - Export PDF (jsPDF + html2canvas) y CSV (papaparse) - Persistencia en IndexedDB (Dexie) - 268 tests unitarios/integración + 6 E2E con Playwright - Deploy: https://process-cost-platform.pages.dev Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
