## Summary
Fixes the Playwright update workflow broken by #5960. When triggered by
adding the "New Browser Test Expectations" label, the workflow was left
in a detached HEAD state, causing `git push` to fail.
## Changes
- **Restores branch checkout for label triggers**: Uses
`github.head_ref` to fetch and checkout the branch when triggered by
`pull_request` events
- **Preserves comment trigger functionality**: Keeps `gh pr checkout`
for `issue_comment` events using `github.event.issue.number`
- **Event-specific push logic**: Uses explicit `git push origin HEAD:${{
github.head_ref }}` for label triggers, plain `git push` for comment
triggers
## Root Cause
PR #5960 removed the original branch checkout logic:
```yaml
git fetch origin ${{ github.head_ref }}
git checkout -B ${{ github.head_ref }} origin/${{ github.head_ref }}
git push origin HEAD:${{ github.head_ref }}
```
This left the label-triggered workflow in detached HEAD after
`actions/checkout@v5`, breaking the push step.
## Testing
This fix properly uses `github.head_ref` only when it's available
(`pull_request` events) and `github.event.issue.number` only for
`issue_comment` events where `head_ref` isn't available.
Fixes#5960

This refactoring improves the CI/CD workflow structure by:
- Split the monolithic setup-frontend action into two focused actions:
- setup-frontend: Now only handles frontend dependency installation and building
- setup-comfyui-server: New action for ComfyUI server setup and launch
- Simplified workflow structure with better separation of concerns:
- Frontend and server setup are now independent and reusable
- Each action has clearer responsibilities and inputs
- Removed duplicate setup code across workflows
- Improved tests-ci.yaml workflow:
- Uses cache/save and cache/restore for the entire workspace
- Test jobs now restore cached build instead of rebuilding
- Reduced redundant setup steps in each test shard
- Better parallelization with faster test execution
- Updated all locale update workflows to use new action structure
- Made setup-playwright a standalone reusable action
Benefits:
- Faster CI runs by reducing redundant builds
- More maintainable with DRY principle
- Easier to debug individual components
- Better action reusability across workflows
This PR introduces a reusable composite action for Playwright setup to
reduce duplication across workflows.
## Changes
- Created `.github/actions/setup-playwright/action.yml` composite action
that:
- Detects or uses provided Playwright version
- Caches Playwright browsers with intelligent cache keys
- Installs browsers only when cache miss occurs
- Installs OS dependencies when cache hit occurs
## Technical Details
- **Important:** The composite action requires `shell: bash` for all
`run` steps as per [GitHub Actions requirements for composite
actions](https://docs.github.com/en/actions/creating-actions/creating-a-composite-action#creating-an-action-metadata-file).
This is a mandatory field for composite actions, unlike regular workflow
steps.
- Updated workflow paths to account for repository checkout locations
(some workflows checkout to subdirectories like `ComfyUI_frontend/`)
- Uses conditional caching to avoid redundant browser installations
## Benefits
- Reduces code duplication across 6 workflow files
- Centralizes Playwright caching logic
- Consistent browser setup across all workflows
- Easier maintenance and updates
- Faster CI runs through intelligent caching
## Affected Workflows
- `.github/workflows/test-ui.yaml` (2 uses)
- `.github/workflows/i18n-custom-nodes.yaml`
- `.github/workflows/i18n-node-defs.yaml`
- `.github/workflows/i18n.yaml`
- `.github/workflows/test-browser-exp.yaml`
