Improve chat_history E2E test stability with toPass() retry (#2699)

## Summary - Replaces static timeout-based wait with toPass() retry logic for ArrowUp navigation wrap test - Makes the test more resilient to timing variations with the BeautifulMentionsPlugin - Uses aria-selected attribute for more reliable selection detection ## Test plan - Run `npm run e2e -- chat_history.spec.ts` to verify the test passes - The test should be more stable and less prone to flakiness 🤖 Generated with [Claude Code](https://claude.com/claude-code)  --- <a href="https://app.devin.ai/review/dyad-sh/dyad/pull/2699" target="_blank"> <picture> <source media="(prefers-color-scheme: dark)" srcset="https://static.devin.ai/assets/gh-open-in-devin-review-dark.svg?v=1"> <img src="https://static.devin.ai/assets/gh-open-in-devin-review-light.svg?v=1" alt="Open with Devin"> </picture> </a>  Co-authored-by: Will Chen <willchen90@gmail.com> Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>
