Implement CLI commands (egg start, stop, exec, logs, status)

[james-in-a-box]

Summary

The CLI argument parser exists in cli/main.py but all commands return "not yet implemented". Need to implement actual functionality.

Current State

# cli/main.py:68
print(f"Command '{args.command}' not yet implemented")
return 1

Commands to Implement

Core Commands

• egg start - Start gateway + sandbox containers
  • --config <path> - Config file location
  • --private - Enable private network mode
  • -p/--prompt - Run with prompt in non-interactive mode
• egg stop - Stop running containers
• egg status - Show container health and status

Utility Commands

• egg exec <cmd> - Execute command inside sandbox
• egg logs [--follow] - View container logs
• egg config validate - Validate configuration files

Implementation Notes

Commands should:

1. Load configuration from egg.yaml
2. Manage Docker containers (start/stop/exec)
3. Handle network setup (public vs private mode)
4. Provide clear error messages

Dependencies

• Requires Port container and deployment files from gateway-sidecar #27 (container files) to be completed first
• Requires Port network isolation configuration (Squid proxy) #28 (network configs) for private mode

Acceptance Criteria

• egg start launches gateway and sandbox containers
• egg stop cleanly shuts down containers
• egg status shows running state and health
• egg exec runs commands in sandbox
• egg logs streams container output
• Error handling for missing Docker, config errors, etc.

Context

From codebase audit - this is Phase 4 in PR #693 implementation plan.
