研究方向
The issue reports that `yarn list` output does not match `npm ls` in showing the correct dependency tree. Investigate the `list` command implementation in Yarn's source code (likely in `src/cli/commands/list.js`). Compare the logic for deduplication and tree display with npm's behavior. Check for any existing comments or linked PRs (none found). The fix would involve adjusting how Yarn resolves and displays nested dependencies, possibly by iterating over the dependency graph differently.
