[FEATURE] In agents view, /branch and /fork should add the branched chat to the agents view, keeping the original chat accessible

Problem Statement

When using the new claude agents view (amazing feature btw <3), when I use a /branch or /fork it replaces the current chat with the branched chat. The original chat is no longer accessible in agents view, and cannot be resumed (due to this bug https://github.com/issues/created?issue=anthropics%7Cclaude-code%7C60203).

Proposed Solution

However, in agents view, it would make way more sense to add the new branch to the list of chats, so I can quickly navigate in between the original, the branch, and any other branch that I create.

Use Case Example

1. Working on shareholder value feature
2. Want a quick change / adjustment to the feature I am working on (layout issues for example) without taking up my main chat that does the large important stuff.
3. Or if I want to ask follow up questions after a /btw.
4. Branch to fix the small stuff with all of the relevant context from the original chat
5. Quickly go back to original chat to continue work
