code cells (Shiki-highlighted with execution count gutter), and
outputs (text, HTML tables, base64 images, error tracebacks)
- ANSI escape codes stripped from error output
- Source toggle shows raw JSON
- Dark mode support throughout
- New JsonTreeView component with recursive collapsible nodes,
auto-expand depth, and GitHub-themed dark mode colors
- JSON/JSONC/JSON5 files show tree view by default, toggle to
Shiki-highlighted source
- SVG files show rendered preview (DOMPurify-sanitized) by default,
toggle to Shiki-highlighted XML source

Same optimization as the merged ResponseMessage PR: replace JSON.parse(JSON.stringify()) with structuredClone and add an O(1) fast-path check on content before falling back to full JSON.stringify comparison.
Same optimization as ResponseMessage: add O(1) fast-path check on content and done fields before falling back to full JSON.stringify comparison. Avoids expensive serialization when only content changes during streaming.
Replace 7 instances of JSON.parse(JSON.stringify()) deep cloning with the native structuredClone API. All are on cold paths (model selection, file preparation, history saving) but structuredClone is ~2x faster and more readable.
During streaming, every token change triggers a full JSON.stringify comparison on the code block token object. Add an O(1) fast-path check on token.text and token.raw — the fields that actually change during streaming — before falling back to the expensive JSON.stringify comparison for infrequent structural changes.
