Pull request overview

This PR updates Playwright lint diagnostics helpers/tests to reduce flakiness by allowing a lint re-run when diagnostics don’t appear on the first attempt.

Changes:

• Extend waitForLintDiagnosticsIssues to optionally accept a rerunLint callback and retry once if initial lint diagnostics assertions fail.
• Update diagnostics Playwright tests to provide rerunLint (re-triggering component/styles lint) for improved stability.
