[FEATURE] Feature request: font size control in VSCode extension panel

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Problem
The Claude Code panel in VSCode uses a fixed font size that doesn't
follow the editor's font size setting. On larger monitors or for users
who prefer larger text, this makes the panel harder to read compared
to the rest of the IDE.

Proposal
Add a setting to control the font size of the Claude Code panel,
either:

• A dedicated setting (e.g. claude-code.fontSize)
• Or have it inherit from editor.fontSize
• Ideally with keyboard shortcuts (Ctrl/Cmd + +/-) like the editor itself

Use case
I use Claude Code daily for a Laravel SaaS project. I switch between
the editor and the Claude panel constantly, and the font mismatch causes
eye strain over long sessions.
