[plan] Add minimal Playwright visual regression example workflow for Frontend Developer persona

[github-actions]

Objective

Add a minimal Playwright visual regression example to the agentic workflow reference documentation or as a shared snippet to better serve Frontend Developer personas.

Context

From discussion #28538 (Agent Persona Exploration 2026-04-26), the agent persona analysis identified that Frontend Developer scenarios (especially visual regression with Playwright) are underserved compared to Backend/DevOps patterns. The agent instructions reference Playwright support, but there are few example workflows to guide users.

Approach

1. Create a minimal example workflow (e.g., visual-regression-checker.md) that demonstrates:
   • Trigger: pull_request: types: [opened, synchronize]
   • Playwright tool configuration with version pin
   • Network permissions for the app's domain
   • Agent prompt for visual comparison and accessibility snapshot
   • Safe-outputs add-comment with the report
2. Add this to the appropriate examples directory or reference it from .github/aw/github-agentic-workflows.md
3. Ensure the workflow compiles cleanly

Files to Create/Modify

• Create: a visual-regression-checker.md example workflow
• Update: .github/aw/github-agentic-workflows.md to reference the Playwright example in the tools section

Acceptance Criteria

• Example workflow compiles without errors
• Playwright tool is configured with a pinned version
• Network access is appropriately scoped
• A comment safe-output reports the visual regression result
• Workflow is linked or mentioned in agent instructions
