Release v1.5.1 - Control de Acceso Basado en Roles y Correcciones Críticas

🔒 Seguridad:
- Implementación completa de RBAC (Role-Based Access Control)
- Staff interno (ADMIN/AGENT/SUPPORT_MANAGER) accede a todos los tickets del tenant
- Clientes (CLIENT_USER/CLIENT_ADMIN) solo acceden a sus propios tickets
- Restricción de creación/modificación de categories/systems a ADMIN/SUPPORT_MANAGER
- Agregado header X-Tenant-ID en frontend-internal para multi-tenancy

🐛 Correcciones:
- Fix crítico: Prevención de números de ticket duplicados
- Implementado retry logic con 3 intentos en creación de tickets
- Generación de ticket_number basada en MAX existente (no contador simple)
- Corrección de filtros en GET /tickets según roles

✨ Mejoras:
- Validación robusta de permisos en todos los endpoints
- Mejor manejo de excepciones y mensajes de error
- Multi-tenancy reforzado con validaciones adicionales

📚 Documentación:
- Agregado CHANGELOG.md con historial de versiones
- Actualizada versión a 1.5.1 en package.json y pyproject.toml
- Scripts de prueba para validación de RBAC

+# Configuración Avanzada de GitHub Copilot para ServiceManagerWeb
+
+## Variables de Contexto Importantes
+
+### Configuración del Sistema
+```env
+# Variables críticas a considerar
+DATABASE_URL=postgresql+asyncpg://user:pass@localhost:5432/servicemanager
+REDIS_URL=redis://localhost:6379/0
+JWT_SECRET_KEY=your-secret-key
+TENANT_ISOLATION=strict
+CORS_ORIGINS=["http://localhost:3000", "http://localhost:3001"]
+```
+
+### Modelos de Datos Clave
+
+#### User Model Completo
+```python
+class User(Base):
+    __tablename__ = "users"
+    
+    id: Mapped[int] = mapped_column(primary_key=True)
+    tenant_id: Mapped[int] = mapped_column(ForeignKey("tenants.id"))
+    email: Mapped[str] = mapped_column(unique=True, index=True)
+    role: Mapped[UserRole] = mapped_column(default=UserRole.CLIENT_USER)
+    is_active: Mapped[bool] = mapped_column(default=True)
+    created_at: Mapped[datetime] = mapped_column(default=datetime.utcnow)
+```
+
+#### Ticket Workflow States
+```python
+class TicketStatus(str, Enum):
+    OPEN = "open"
+    IN_PROGRESS = "in_progress" 
+    PENDING_CLIENT = "pending_client"
+    RESOLVED = "resolved"
+    CLOSED = "closed"
+    CANCELLED = "cancelled"
+```
+
+## Reglas de Implementación Específicas
+
+### 1. Multi-Tenancy Estricto
+- NUNCA hacer queries sin filtrar por `tenant_id`
+- Middleware de tenant debe estar en toda request
+- Validar permisos a nivel de tenant antes de operaciones
+
+### 2. Audit Trail Obligatorio
+```python
+async def log_audit_event(
+    action: str,
+    resource_type: str,
+    resource_id: int,
+    user_id: int,
+    tenant_id: int,
+    details: dict = None
+):
+    # Implementar en todas las operaciones CRUD críticas
+```
+
+### 3. Error Handling Consistente
+```python
+# Backend
+raise HTTPException(
+    status_code=status.HTTP_403_FORBIDDEN,
+    detail="Insufficient permissions for tenant resource"
+)
+
+# Frontend  
+import { toast } from '$lib/stores/toast';
+toast.error("Error al procesar la solicitud");
+```
+
+### 4. Performance Patterns
+```python
+# Queries con paginación siempre
+async def get_tickets_paginated(
+    db: AsyncSession,
+    tenant_id: int,
+    skip: int = 0,
+    limit: int = 20
+) -> Tuple[List[Ticket], int]:
+    # Select con join optimizado + count total
+```
+
+## Componentes Frontend Reutilizables
+
+### Layout Structure
+```
++layout.svelte (global)
+├── Header.svelte (navigation)
+├── Sidebar.svelte (menu)  
+└── Toast.svelte (notifications)
+```
+
+### Form Patterns
+```typescript
+// Validation con Zod
+const createTicketSchema = z.object({
+  title: z.string().min(5).max(200),
+  description: z.string().min(10),
+  priority: z.nativeEnum(TicketPriority),
+  category_id: z.number().positive()
+});
+```
+
+## Debugging y Logging
+
+### Backend Logging
+```python
+import structlog
+logger = structlog.get_logger(__name__)
+
+# En cada endpoint
+logger.info(
+    "ticket_created",
+    ticket_id=ticket.id,
+    user_id=current_user.id,
+    tenant_id=current_user.tenant_id,
+    correlation_id=request.correlation_id
+)
+```
+
+### Frontend Error Boundary
+```svelte
+<!-- En +layout.svelte -->
+{#if $page.error}
+  <ErrorComponent error={$page.error} />
+{/if}
+```
+
+## Comandos de Desarrollo Específicos
+
+```bash
+# Backend development
+cd backend && uvicorn app.main:app --reload --port 8000

+cd frontend-client && npm run dev -- --port 3000
+
+# Workers
+cd workers && celery -A app.celery worker --loglevel=info
+
+# Full stack con Docker

+## Configuración de IA Especializada
+
+### Prioridades de Asistencia
+1. **Seguridad primero**: Siempre implementar autenticación/autorización en nuevos endpoints
+2. **Multi-tenancy**: Verificar aislamiento de datos entre tenants en toda nueva funcionalidad
+3. **Performance**: Considerar impacto en bases de datos grandes (índices, paginación, caching)
+4. **Auditabilidad**: Registrar acciones sensibles en el sistema de audit
+5. **Escalabilidad**: Código preparado para crecimiento empresarial
+
+### Patrones Preferidos
+
+#### Backend (FastAPI)
+```python
+# Estructura de endpoint típica
+@router.post("/", response_model=schemas.TicketResponse)
+async def create_ticket(
+    ticket: schemas.TicketCreate,
+    current_user: models.User = Depends(get_current_user),
+    db: AsyncSession = Depends(get_db)
+):
+    # 1. Validar permisos multi-tenant
+    # 2. Procesar lógica de negocio
+    # 3. Audit log
+    # 4. Return response
+```
+
+#### Frontend (SvelteKit)
+```typescript
+// Store pattern con Zod validation
+import { z } from 'zod';
+import { writable } from 'svelte/store';
+
+const TicketSchema = z.object({
+  title: z.string().min(5),
+  priority: z.enum(['LOW', 'MEDIUM', 'HIGH', 'URGENT'])
+});
+```
+
+### Contexto de Archivos Clave
+
+#### Backend Core
+- `app/core/security.py`: JWT, permissions, rate limiting
+- `app/middleware/tenant.py`: Multi-tenant context
+- `app/models/`: SQLAlchemy models con relationships
+- `app/api/v1/endpoints/`: Endpoints REST por dominio
+
+#### Frontend Routing
+- `frontend-internal/`: Panel administrativo interno
+- `frontend-client/`: Portal de clientes
+- Ambos usan SvelteKit con layout compartido
+
+#### Workers/Tasks
+- `workers/app/tasks/`: Tareas Celery asíncronas
+- `email_tasks.py`: Notificaciones y plantillas
+- `sla_tasks.py`: Monitoreo de SLAs automático
+
+### Troubleshooting Común
+
+#### Database Issues
+```bash
+# Reset migrations
+docker-compose exec backend alembic downgrade base
+docker-compose exec backend alembic upgrade head
+```
+
+#### Multi-tenant Debug
+- Verificar `tenant_context` middleware
+- Headers: `X-Tenant-ID` en requests
+- Queries siempre filtrar por tenant_id
+
+#### Frontend Build Errors
+```bash
+cd frontend-internal && npm run build
+cd frontend-client && npm run build
+```
+
+### Convenciones de Desarrollo
+
+#### Naming
+- **Models**: PascalCase (User, Ticket, TenantOrganization)
+- **Endpoints**: kebab-case (/api/v1/user-management/)
+- **Components**: PascalCase.svelte (TicketCard.svelte)
+- **Stores**: camelCase (ticketStore.ts)
+
+#### Error Handling
+- Backend: HTTPException con status codes apropiados
+- Frontend: Toast notifications para UX
+- Logs: Structured logging con correlation IDs
+
+#### Testing Strategy
+- Unit: Lógica de negocio y validaciones
+- Integration: Endpoints completos con DB
+- E2E: Flujos críticos multi-tenant
+
 Cuando trabajes en este proyecto, siempre considera la naturaleza multi-tenant y empresarial del sistema.
