Description:

To improve developer onboarding and cross the chasm to the early majority, we need to implement a phala init command for our scaffold project.

Objective:

Create a simple command that quickly initializes and starts a new Phala Cloud project.

Requirements:

1. Implement phala init to:
   • Create project directory
   • Set up basic structure and config files
   • Install dependencies
2. Add interactive customization prompts
3. Provide concise documentation
4. Ensure IDE/editor compatibility
5. Include tests

Success Metrics:

• Reduced project setup time
• Increased user adoption
• Positive user feedback

unsolicited suggestion: your guide uses a basic nodejs app. perhaps publish a tagged docker image, akin to whoami that shows some output that is unique to running in a TEE.

Great idea. I'll setup a github action for this as well.
