Feature request: split panes for chats in the same project

Description

Hi T3 Code team, and thank you for building this. It has become a core part of my daily workflow.

I would like to politely request a split pane view, so that two or more chats from the same project can be shown side by side in one window.

Use Case

Pinning works well for the few chats that matter most in a project. But for a single issue or a single piece of development work, I often need 3-4 parallel worktrees, each with its own chat. Today I have to switch between them one at a time, which means:

• I lose sight of what the other chats are doing while I read one.
• I have to hold the state of the other threads in my head.
• Comparing outputs or handing context from one chat to another takes extra clicks.

A split pane would let me watch and steer several chats at once. I expect this to help both productivity (less switching) and accuracy (fewer mistakes from losing track of which chat is doing what).

Suggested shape (open to any approach)

• Open a chat in a new pane, for example from the thread context menu or by dragging it to the edge.
• Horizontal or vertical splits, with resizable panes.
• Panes limited to chats from the same project, which keeps scope small.
• Pinning stays as it is, for the handful of chats that matter most.

Thanks for considering it. Happy to give more detail or test an early build.
