fix: deflake E2E tests (partial_response.spec.ts) (#2907)

## Summary - Updated stale aria snapshot for `partial_response.spec.ts` that was consistently failing - Button text content now renders actual text (e.g., `file1.txt file1.txt`, `Edit`, `Undo`, `Retry`) instead of empty strings - Removed `wrote 1 file(s)` text entries that no longer appear in the UI ## Context Scanned 5 recent CI runs on main and 13 open PRs by wwwillchen/wwwillchen-bot/dyadbot. Found flaky tests across 16+ spec files. Most flakiness is CI-specific (timing/load dependent) and cannot be reproduced locally with 10x repeats. The `partial_response.spec.ts` snapshot was the only consistently broken test. ## Test plan - [x] `partial_response.spec.ts` passes 10/10 times locally with updated snapshot - [x] Full E2E suite passes (236/243, with only transient flaky failures unrelated to this change) 🤖 Generated with [Claude Code](https://claude.com/claude-code)  --- <a href="https://app.devin.ai/review/dyad-sh/dyad/pull/2907" 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: claude[bot] <41898282+claude[bot]@users.noreply.github.com> Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
