Resizable Chat Pane Width for Better Large-Screen Productivity

I'd like the chat conversation pane to support freely adjustable width.

On large displays (such as 27–32" monitors or Apple's larger MacBook/Studio Display setups), the current fixed conversation width leaves a significant amount of unused horizontal space. Long responses, code explanations, research discussions, and documentation require excessive vertical scrolling because each line wraps much earlier than necessary.

Allowing users to drag the conversation pane to their preferred width (or choose from several width presets) would make much better use of large screens and significantly improve readability and productivity. This would be especially valuable for users who spend long periods reading detailed technical explanations or reviewing long conversations.

A possible implementation could be:

Draggable conversation pane width.
Optional width presets (Compact / Default / Wide / Full Width).
Remember the user's preferred width across sessions.

This would be a relatively small UX improvement but would have a noticeable impact on the desktop experience, especially for power users with large monitors.
