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
