Greptile Overview

Greptile Summary

This PR enables Playwright trace recording for failed tests in CI, which will significantly improve debugging capabilities for test failures. The implementation is straightforward and follows Playwright best practices.

Key Changes:

• Added trace: "retain-on-failure" to Playwright config to capture trace files only when tests fail
• Configured outputDir: "test-results" to ensure traces are saved in the correct location
• Updated GitHub workflow artifact upload to include trace files with updated comment
• Minor whitespace cleanup in workflow file (trailing spaces removed)

The test-results directory is already properly gitignored, and the artifact retention is set to 30 days, which is appropriate for debugging purposes.

Confidence Score: 5/5

• This PR is safe to merge with no risk - it only adds test debugging capabilities
• The changes are minimal, well-scoped, and follow Playwright's official documentation. The trace recording only activates on test failures, adding no overhead to passing tests. The configuration is already supported by the existing gitignore rules, and the workflow changes are purely additive.
• No files require special attention
