[Delta] ACP agents & terminal thread support

[ShihaoShenCreator]

Body

This is a feature request for Delta, not for Zed.

What are you proposing?

Add ACP agents and terminal thread support in Delta.

Why does this matter?

Currently, we CANNOT use 3rd-party agents in Delta directly. With ACP agents and terminal thread support (just like Zed), we can do it.

Are there any examples or context?

You can see Zed to know how it should be like.

Possible approach

You can see Zed to know how it should be like.
