[Optional] Provide reference docker-compose for full stack

[VirtualAgentics]

Description

Create a reference docker-compose setup with the full production stack for easy local development and testing.

Background

Developers need an easy way to run the full production stack locally. A docker-compose setup provides instant access to all services.

Requirements

• Create docker-compose.yml with app + Redis + Postgres + Prometheus
• Configure all services with production-like settings
• Add volume mounts for persistence
• Include Grafana for metrics visualization
• Document setup and usage
• Add healthchecks for all services
• Add environment configuration

Implementation Details

Files to modify:

• docker-compose.yml - Full stack compose
• docker-compose.override.yml - Development overrides
• docs/development/ - Development documentation
• README.md - Development setup
• scripts/ - Development scripts

Technical approach:

• Create comprehensive docker-compose setup
• Add service dependencies and health checks
• Configure persistent volumes
• Add monitoring stack
• Create development documentation

Acceptance Criteria

• Compose brings up full stack
• All services are healthy
• Persistence works correctly
• Monitoring is accessible
• Documentation is complete

Testing Requirements

• Compose startup tests
• Service health tests
• Persistence tests
• Monitoring tests

Documentation Updates

• README.md - Development setup
• Development guide - Local setup
• Monitoring guide - Metrics access
• Troubleshooting guide - Common issues
