Fix terminal resizing crash in TUI app

Fix terminal resizing crash in TUI app

Description

Rapidly resizing the terminal while the TUI is running can cause layout calculation errors and crashes in Textual. Add a resize debounce handler that delays layout recalculation until resizing settles (200ms debounce) and catches layout errors gracefully.

Role: frontend
Model: sonnet
Tests: All 17 tests pass (previously 11 passed + 6 skipped). Now let me run lint:

Summary

The pull request addresses a critical issue that causes the TUI (Text User Interface) application to crash during terminal resizing events. By implementing proper error handling and state management during these events, the change enhances the robustness and user experience of the application.

Risk Assessment

Medium: While the fix is aimed at preventing crashes, any changes around terminal interactions can introduce new UI behavior issues. There's a potential for regression if other parts of the application rely on the previous handling of resize events.

Actionable Recommendations

• Thorough Testing: Ensure comprehensive tests are added that simulate various terminal resizing scenarios.
• Code Review: Have another maintainer double-check the error handling logic to ensure all edge cases are addressed.
• Documentation: Update the relevant sections of the documentation to reflect any changes in TUI behavior due to the fix.
• User Feedback: After merging, gather user feedback to monitor for any unexpected changes in usability.
• Versioning
