Feature request: configurable chat font family in VSCode extension

Summary

The Claude Code VSCode extension chat panel uses a proportional font by default.
When Claude outputs tables or aligned layouts, the rendering breaks because
proportional fonts don't preserve column alignment.

Expected behavior

A setting such as \claudeCode.chatFontFamily\ that allows users to specify a
monospace font (e.g. Consolas, \"Courier New\", monospace) for the chat panel.

Suggested setting

\\\json
"claudeCode.chatFontFamily": "Consolas, 'Courier New', monospace"
\\\

Workaround

Currently none available without third-party extensions like Custom CSS and JS Loader,
which requires re-applying after every VSCode update.

Environment

• Extension version: 2.1.143
• OS: Windows 11 (WSL2)
