Add comprehensive database rebuild capability with complete unified schema

Features:
- Complete SQL schema file (000_complete_schema.sql) for full database rebuild
- Unified authentication system with UUID-based users, API keys, refresh tokens
- All platform tables: users, agents, workflows, tasks, executions, metrics, alerts
- Comprehensive indexing strategy for performance optimization
- Automated rebuild scripts (Python and Shell) with Docker integration
- Detailed documentation with usage instructions and troubleshooting

Schema capabilities:
✅ UUID-based design for scalability and consistency
✅ Complete authentication: JWT, API keys, password hashing, token blacklisting
✅ Agent management: Ollama and CLI agents with performance metrics
✅ Workflow orchestration: n8n integration with execution tracking
✅ Task management: Priority-based assignment and status tracking
✅ Monitoring: System alerts, performance metrics, health checks
✅ Default users: admin and developer accounts for immediate access

This provides a single-command database rebuild capability that creates
the complete Hive platform schema from scratch, resolving all previous
schema conflicts and providing a clean foundation for authentication
and full platform functionality.

+# Hive Database Schema Management
+
+This directory contains database schema files and migration scripts for the Hive platform.
+
+## Files Overview
+
+### Schema Files
+- `000_complete_schema.sql` - **Complete database schema from scratch**
+- `001_initial_schema.sql` - Original initial schema (legacy)
+- `002_add_auth_fields.sql` - Migration to add authentication fields (legacy)
+
+### Scripts
+- `../scripts/rebuild_database.sh` - Shell script to rebuild database using Docker
+- `../scripts/rebuild_database.py` - Python script to rebuild database
+
+## Complete Database Rebuild
+
+The `000_complete_schema.sql` file contains the **complete, unified database schema** that includes:
+
+✅ **Unified User Management**
+- UUID-based user IDs
+- Complete authentication fields (username, email, passwords)
+- User roles and permissions (is_active, is_superuser, is_verified)
+- Backward compatibility fields (role, full_name)
+
+✅ **Authentication System**
+- API keys with scoped permissions
+- JWT refresh tokens with device tracking
+- Token blacklisting for security
+- Comprehensive usage tracking
+
+✅ **Agent Management**
+- AI agent registration and configuration
+- Performance metrics and monitoring
+- Support for both Ollama and CLI agents
+
+✅ **Workflow & Task Management**
+- Workflow definitions with n8n integration
+- Execution tracking and monitoring
+- Task assignment and status management
+
+✅ **Monitoring & Alerting**
+- System alerts and notifications
+- Performance metrics collection
+- Agent health monitoring
+
+## Usage
+
+### Option 1: Docker-based Rebuild (Recommended)
+
+```bash
+# From the backend directory
+cd /path/to/hive/backend
+./scripts/rebuild_database.sh
+```
+
+This script:
+- Connects to the PostgreSQL service in Docker swarm
+- Executes the complete schema rebuild
+- Verifies the installation
+- Shows initial user credentials
+
+### Option 2: Python Script
+
+```bash
+# Set environment variables if needed
+export DB_HOST=localhost
+export DB_PORT=5432
+export DB_NAME=hive
+export DB_USER=postgres
+export DB_PASSWORD=hive123
+
+# Run the Python script
+python scripts/rebuild_database.py
+```
+
+### Option 3: Manual SQL Execution
+
+```bash
+# Connect to PostgreSQL and execute directly
+psql -h localhost -U postgres -d hive -f migrations/000_complete_schema.sql
+```
+
+## Default Users
+
+After rebuild, the database will contain:
+
+| Email | Username | Password | Role | Permissions |
+|-------|----------|----------|------|-------------|
+| admin@hive.local | admin | admin123 | admin | Superuser, Active, Verified |
+| developer@hive.local | developer | dev123 | developer | Active, Verified |
+
+**⚠️ SECURITY: Change these default passwords immediately in production!**
+
+## Schema Features
+
+### UUID-based Design
+- All primary entities use UUIDs for better scalability
+- Consistent identification across distributed systems
+- No integer ID conflicts in multi-node deployments
+
+### Complete Authentication
+- Password hashing with bcrypt
+- API key generation with prefixes (hive_xxx)
+- JWT token management with refresh and blacklisting
+- Scoped permissions for fine-grained access control
+
+### Performance Optimized
+- Comprehensive indexing strategy
+- Efficient queries for common operations
+- Time-series optimization for metrics
+- Proper foreign key relationships
+
+### Monitoring Ready
+- Built-in metrics collection
+- Alert management system
+- Agent performance tracking
+- Execution monitoring
+
+## Migration from Legacy Schema
+
+If you have an existing database with the old schema, the complete rebuild will:
+
+1. **Drop existing tables** (⚠️ DATA LOSS)
+2. **Create unified schema** with all new features
+3. **Insert default users** for immediate access
+
+For production systems with existing data, consider:
+- Creating a backup before rebuild
+- Developing custom migration scripts
+- Using the incremental migration files instead
+
+## Troubleshooting
+
+### Connection Issues
+- Ensure PostgreSQL service is running
+- Check network connectivity to database
+- Verify credentials and database name
+
+### Permission Errors
+- Ensure user has CREATE/DROP privileges
+- Check database ownership
+- Verify network policies allow connections
+
+### Schema Conflicts
+- Use complete rebuild for clean installation
+- Check for existing databases/schemas
+- Ensure proper cleanup of old installations
+
+## Next Steps
+
+After successful database rebuild:
+
+1. **Change default passwords**
+2. **Configure authentication settings**
+3. **Register AI agents**
+4. **Create initial workflows**
+5. **Set up monitoring dashboards**
+
+The unified schema provides a solid foundation for the complete Hive platform with authentication, agent management, and workflow orchestration.
