This pull request makes a small change to the
`.github/workflows/pr-update-playwright-expectations.yaml` file,
removing the unconditional `if: always()` condition from the
`merge-and-commit` job. This means the job will now only run if its
dependencies succeed, rather than always running regardless of previous
job outcomes.
This pull request significantly refactors the Playwright expectations
update workflow to improve reliability, efficiency, and maintainability.
The workflow is now split into three coordinated jobs—setup, sharded
snapshot updates, and merge/commit—enabling parallel test execution and
artifact management. Key improvements include sharding Playwright
snapshot updates, robust caching and artifact handling, and more
reliable PR context handling.
**Workflow Restructuring and Sharding:**
* The workflow is split into three jobs: `setup` (prepares environment
and caches it), `update-snapshots-sharded` (runs Playwright snapshot
updates in four parallel shards), and `merge-and-commit` (merges results
and commits updates). This enables faster, more reliable snapshot
updates.

**Caching and Artifact Management:**
* The setup job builds and caches the entire workspace, which is then
restored by each shard for consistent environments. Each shard uploads
its updated snapshots and test reports as artifacts, which are later
downloaded and merged in the final job.
**Improved PR Context Handling:**
* PR number, branch, and comment IDs are now reliably extracted and
passed between jobs using outputs, ensuring correct association with the
PR throughout the workflow (e.g., for commenting, reactions, and pushing
updates).

**Job and Step Renaming/Cleanup:**
* The main job is renamed from `test` to `setup`, and redundant or
unnecessary steps (such as the old branch SHA extraction) are removed
for clarity and maintainability.

**Comment and Label Automation Improvements:**
* Automated GitHub comment reactions and label removals now use the
correct PR context, ensuring that feedback and status updates are
reliably posted to the right place.
