Feature request: option to disable hover-triggered sidebar reveal

Problem

In the Codex desktop app on Windows, the left sidebar reappears whenever the mouse pointer passes over the left edge after the sidebar has been hidden. This is easy to trigger accidentally and interrupts work.

Requested behavior

Please add a setting such as "Open sidebar on hover". When disabled, the sidebar should open only through the toolbar button or the keyboard shortcut (currently Ctrl+B on Windows).

Why this matters

Some users prefer a deliberate, keyboard- or click-only sidebar toggle. The current hover reveal makes it difficult to keep the sidebar out of the way while moving the mouse around the window.
