Validate E2E Skill

Use this skill to interactively validate that implemented features work correctly by navigating the UI and verifying expected behavior.

What This Skill Does

1. Receives the UI endpoint URL from Aspire runtime (typically https://localhost:3000)
2. Receives feature context/requirements from the user or implementation notes
3. Uses Playwright MCP browser tools to navigate the UI
4. Executes feature-specific validation flows tailored to the requirements
5. Verifies UI state changes, element properties, API responses
6. Reports validation results (pass/fail per step) with evidence
7. Exits with failure if any assertions fail or expected behavior is not observed
