[FEATURE] Independent zoom for main panel vs sidebar in desktop app (code)

Problem Statement

When using the Claude Code desktop app, the zoom shortcut scales the entire UI - both the main conversation panel and the sidebar together. This forces an uncomfortable tradeoff: if I zoom in to make the conversation text large enough to read comfortably during long sessions, the sidebar also grows and I can see far fewer sessions, files, and chapters at a glance. If I keep zoom low to preserve sidebar density, the main panel text becomes harder to read.

The main panel and sidebar serve very different purposes - one is for focused reading of long-form content, the other is a compact navigation surface - so they have different ideal text sizes.

Environment: Claude Code desktop on macOS, MacBook Air M1, 16 GB RAM.

Proposed Solution

Allow the main panel and sidebar to be zoomed independently.
Ideal interaction:

• Cmd +/- (the existing zoom shortcut) zooms only the main conversation panel text, leaving the sidebar untouched.
• A separate shortcut (e.g. Cmd+Shift +/-) zooms the sidebar if needed.
• Zoom levels persist across sessions.
• A settings entry shows current zoom levels for each pane and lets the user reset them.

This lets me make the conversation text comfortably large for reading while keeping the sidebar compact and information-dense.
