feat(platform): Enhance GitHub Copilot agent setup with CI-aligned environment and comprehensive platform documentation integration (#10708)

This PR transforms GitHub Copilot from a general coding assistant into a
platform-specific expert by providing comprehensive onboarding and a
fully configured development environment that mirrors the AutoGPT
platform's CI/CD pipeline.

## Key Features

### CI-Aligned Development Environment
- **Production-Grade Setup**: The `copilot-setup-steps.yml` workflow now
mirrors the platform's CI workflows, providing Copilot with the same
environment used for testing and deployment
- **Essential Services**: Automatically starts Docker services
(PostgreSQL, Redis, RabbitMQ, ClamAV) required for platform development
- **Database Readiness**: Includes Prisma migrations and client
generation to ensure the database is immediately usable
- **Environment Configuration**: Copies default environment files and
validates service health, eliminating manual setup steps

### Comprehensive Platform Knowledge
- **Unified Documentation**: The `copilot-instructions.md` file
integrates knowledge from multiple sources (installer.md,
advanced_setup.md, CLAUDE.md, AGENTS.md) into a single comprehensive
guide
- **Development Patterns**: Includes advanced patterns for block
development, API creation, frontend work, and security implementation
- **Architecture Insights**: Provides deep understanding of the agent
block system, database schema, middleware, and CI/CD workflows
- **Troubleshooting Guide**: Comprehensive error handling and validation
steps based on production experience

### Enhanced Development Workflow
```bash
# Before: Trial-and-error dependency installation
# After: Fully configured environment ready immediately

# Copilot now understands:
poetry run serve                    # Backend server (port 8000)
pnpm dev                           # Frontend server (port 3000)
docker compose up -d               # Essential services
poetry run pytest backend/blocks/test/test_block.py -xvs  # Block validation
```

## Benefits

This configuration provides Copilot with:
- **Immediate Productivity**: No time wasted on environment setup or
dependency discovery
- **Platform Expertise**: Deep understanding of AutoGPT's architecture,
security patterns, and development workflows
- **CI Consistency**: Local development environment matches production
testing environment
- **Comprehensive Context**: Access to all platform documentation and
development patterns in a single source

The setup eliminates the slow trial-and-error process typical of
LLM-based development tools and ensures Copilot works efficiently from
the first interaction.
