[victordibia]

This PR extends AGS with the following

• Refactor playground/sessions to add a hidable sidebar with a list of sessions for easy switching across sessions
• Adds a dedicated page for teams
  • Enables switching between modifying raw JSON config for teams and
  • Visual drag and drop view that enables users drag in items from a Component gallery to an agent

1. In team builder, when "New Team" is clicked, you should auto save changes so it shows up on left side pannel.

Otherwise you keep pressing New Team and nothing shows up until you find the save button.

I think changes should be probably be saved by default at each action.

2. How to change team name in visual builder?

Couldnt figure it out, had to go to json to change it.

3. In the react flow component, when you press the "..." icon on top right, it freezes and keep reloading (the one that shows auto layout...)

4. On the components, why is the "Team" not a component?

I couldn't figure out how to change the team type.

5. I expected to be able to change the system message for the assistant agent in the builder, but could not. Similarly for other things that are not drag dropable. Like the agent name, max messages...

6. Error messages that team configuration is not valid are not there. For instance I created a team with two agents with same name. I couldn't run it and no relevant error messages showed up

Looks good. Still, it is a pain for low/no code user to install AutoGen studio. Can we have release dmg or pkg or exe files?

Added the following fixes

• Editing components: There is now a v1 implementation for a component editor .. each component now has an edit button that when clicked will enable update …
• Fix … issue where menu in visual builder is stuck.
• Validation .. will be addressed in a future PR .. tracked in issue Add validation UX +API for all components in AGS #4616
• DMG/exe — good idea, will I have an issue to track - Improve installation of AGS via a bundled dmg or exe file #4621
• Components .. why is team not a component .. This is mostly because the team is the high level component .. it cannot be “dragged into any other component”. A future PR will expand team sidebar to show teams from a configurable 3rd party store of teams Ability to attach 3rd party or local gallery of components to AGS #4203
• New team .. autosaves the team on create.
