Add Option to Increase Chat Width

Feature summary

Allow users to increase the chat width beyond the current default size for improved readability of code, logs, and other wide content.

What problem are you trying to solve?

Currently, the chat panel supports a fixed/default width and can be reduced in size, but there is no option to increase the width beyond the default.

For users working with code snippets, logs, JSON payloads, tables, or long technical discussions, the current width can be limiting and results in excessive line wrapping.

Requested enhancement:

Add a setting or draggable resize handle that allows increasing the chat width beyond the current default.
Ideally, support multiple width presets (e.g. Narrow, Default, Wide, Extra Wide) or a fully resizable layout.
Persist the selected width between sessions.

Proposed solution

Add a setting or draggable resize handle that allows increasing the chat width beyond the current default.
Ideally, support multiple width presets (e.g. Narrow, Default, Wide, Extra Wide) or a fully resizable layout.
Persist the selected width between sessions.

Additional context

No response

No files, tests, or entry points are named. Start by locating the chat panel layout and its existing width or resize behavior, then inspect how user settings are persisted. Done means users can increase the width beyond the current default and the selected width remains after restarting the app.
