Add main README documentation for ALPHA3 project

[Copilot]

The repository lacked root-level documentation explaining what ALPHA3 is and how to use it.

Changes

• README.md: Comprehensive Spanish documentation (334 lines) covering:
  • Project overview: Real-time collaborative project management system with hierarchical structure (Projects → Categories → Tasks)
  • Tech stack: React 19 + Vite frontend, Node.js + Express backend, Supabase PostgreSQL, Socket.io for WebSocket sync
  • Complete setup instructions with database schema
  • API reference for 3 REST endpoints and 2 WebSocket events
  • Deployment configuration for Render

@copilot Como lo puedo implementar

La funcionalidad ya está implementada y lista para usar. He creado documentación detallada en los archivos CREAR_PROYECTO.md y GUIA_VISUAL.md.

Pasos para implementar:

1. Configurar la base de datos (Supabase):

   • Asegúrate de tener la tabla projects creada
   • Configura las credenciales en server/.env

2. Instalar dependencias:

   cd server && npm install
   cd ../client && npm install

3. Iniciar la aplicación:

   # Terminal 1
   cd server && npm start
   
   # Terminal 2
   cd client && npm run dev

4. Usar la funcionalidad:

   • Ve al Dashboard (http://localhost:5173)
   • Haz clic en el botón "+ Nuevo Proyecto" (esquina superior derecha)
   • Ingresa el nombre del proyecto
   • Haz clic en "Crear"

El proyecto aparecerá inmediatamente en el menú lateral con 0% de progreso, listo para agregar categorías y tareas.

Consulta GUIA_VISUAL.md para una guía paso a paso completa con diagramas.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• placeholder
  • Triggering command: /usr/local/bin/node node server.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
