Subject: [PATCH 2/2] fix(032): resolve CodeRabbit findings - ARIA semantics
 and accessibility
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fix ARIA live region semantics: only set aria-live="polite" for non-alert status
- Role="alert" already implies aria-live="assertive", setting aria-live="polite" contradicts this
- Removes double-speaking issues on screen readers (VoiceOver iOS)
- Dismiss button UI and functionality preserved

All tests passing: 452/452 ✓
