[Feature Request] Support moving third-party extension panels (e.g., Cline, Codex) to the secondary sidebar (right panel)

[eunos-1128]

Summary

In Windsurf, third-party extension panels such as Cline and Codex cannot be moved to the secondary sidebar (right panel), whereas this is easily achievable in VS Code and Cursor.

Current Behavior

• Extension panels (e.g., Cline, Codex) cannot be dragged or moved to the right (secondary) sidebar in Windsurf.
• There is no "Move to Secondary Sidebar" or equivalent option available via right-click or any menu.

Expected Behavior

• Users should be able to move third-party extension panels to the secondary sidebar (right panel), in the same way VS Code and Cursor allow this.

Steps to Reproduce

1. Install a third-party extension that provides a side panel (e.g., Cline or Codex).
2. Attempt to move the extension panel to the right (secondary) sidebar.
3. Observe that there is no option or drag-and-drop support to do so.

Environment

• Windsurf Version: 1.9577.43 (Commit: 1.48.2 / 745a6c1ac471cc11f782a05d2c3ceacbc1de308f)

• OS: macOS 15.7.2 (24G325) / 14.2.231.21-electron.0

• Extensions tested: Cline, Codex
