[Feature] Implement cli.sh start, restart, and stop commands with application build process

[iSuperCoder]

Description

Implement lifecycle management commands for the JitAI development environment. The start command should trigger the application build process before starting services.

Requirements

1. cli.sh start

Functionality:

• Check if workspace is properly initialized
• Call builder to execute application build process:
  • Build frontend assets
  • Compile/package backend code
  • Generate necessary configuration files
• Start jitnode runtime engine
• Display startup logs and status
• Verify services are running correctly

2. cli.sh stop

Functionality:

• Gracefully shutdown jitnode
• Stop all related services
• Clean up temporary files if needed
• Display shutdown status

3. cli.sh restart

Functionality:

• Execute stop command
• Wait for complete shutdown
• Execute start command with same parameters

Acceptance Criteria

• cli.sh start successfully builds and starts the application
• cli.sh stop cleanly shuts down all services
• cli.sh restart properly stops and restarts services
• Build process is triggered automatically on start
• Clear error messages for build failures
