Problem

Currently, there is no way to adjust the font size of the Claude Code chat panel
independently from the rest of the VSCode interface. The panel is rendered as a
webview and only responds to the global window.zoomLevel setting, which affects
the entire IDE (editor, sidebar, terminal, etc.).

Expected Behavior

Allow users to configure the font size of the Claude Code chat panel independently,
similar to how VSCode allows separate font size settings for:

• Editor: editor.fontSize
• Terminal: terminal.integrated.fontSize
• Markdown preview: markdown.preview.fontSize

Proposed Solution

Add a setting such as claude-code.chat.fontSize that controls only the font size
within the Claude Code webview panel.

Workarounds

• Using window.zoomLevel (affects everything, not ideal)
• Using Claude Code in the integrated terminal with terminal.integrated.fontSize

Environment

• OS: Windows (WSL2) / Linux
• VSCode Extension

Proposed Solution

Add a setting such as claude-code.chat.fontSize that controls only the font size
within the Claude Code webview panel.
