Merge branch 'main' into bl-selective-snapshot-update

Resolved conflicts in update-playwright-expectations.yaml by:
- Keeping main's improvements: concurrency control, comment reactions, better branch checkout
- Keeping our selective snapshot update logic with validation
- Keeping our workflow summary generation
- Combined both sets of improvements for a robust solution

Fixed eslint configuration issue where vite.config.mts was in both allowDefaultProject and tsconfig.json
