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
## Summary
Extracts shared formatting and network utilities into dedicated
workspace package.
## Changes
- **What**: Created `@comfyorg/shared-frontend-utils` package containing
formatUtil and networkUtil
- **Breaking**: None - utilities remain accessible via path aliases in
`tsconfig`
Split `createAnnotatedPath` and `electronMirrorCheck` out and left in
frontend, due to their tightly-coupled nature. See [discussion on this
PR](https://github.com/Comfy-Org/ComfyUI_frontend/pull/5843#issuecomment-3344724727).
