[Bug] Code block highlighting renders as per-line ribbons instead of continuous rectangle on macOS

Bug Description
In the Claude Code extension in VS Code on macOS, code blocks paint as per-line ribbons. Fenced code blocks shade the inline code element, so multi-line blocks get line-by-line highlighter ribbons (ragged edges, gaps) instead of one continuous rectangle. Repro: ask for any multi-line code block. Fix: put the background on the block-level pre (transparent pre code), or display:block on the fenced code.
