[Weave] Onboarding flow for first time users

Feedback from Suzy

• When I first come to create a new prompt, there should be a description on how to write your own prompt instead of “Press / for commands”

• Proper onboarding process:

• Teach user how to use model

• User don’t understand what’s prompt variable

• Every button should have a guide / onboarding (Select Model, Save Button…)
