Implements a CleanupReport UI component to display detailed cleanup results after test runs, including tables cleaned, records deleted per table, duration, and errors. Integrates with IntegrationTestRunner to show cleanup summary post-run and exports a compact inline view.
Introduce visible countdown indicators for rate-limit delays between tests:
- Extend test runner to emit and expose delay progress updates.
- Update IntegrationTestRunner UI to display countdown while pausing.
- Ensure users see why tests are paused during delays.
Add Markdown formatting utilities for test results, wire up clipboard copy in IntegrationTestRunner, and export new formatters. Introduce formatters.ts, extend index.ts exports, and implement copy all / copy failed / per-test copy functionality with updated UI.
