## Message

```
Use shared Shiki highlighting for chat markdown code blocks

- Replace `rehype-highlight`/`highlight.js` with `@pierre/diffs` highlighter in `ChatMarkdown`
- Add LRU caching and in-flight dedupe for highlighted code, with streaming-aware behavior
- Extract shared diff theme resolution utility and add unit tests for new LRU cache

```
