Add AI-powered PR review system for Playwright + TypeScript

[yhAutomationQA]

Description

Adds an AI PR review system that automatically analyzes pull request diffs for Playwright + TypeScript test framework code. Detects flaky patterns, poor locators, missing assertions, DRY violations, and architecture issues.

Files Added

File	Purpose
.ai/skills/playwright-pr-review.md	Skill definition with severity levels, 7-category review checklist, scoring formula
.ai/prompts/pr-review.prompt.md	Prompt template with diff injection point
.github/PULL_REQUEST_TEMPLATE.md	Structured PR template with flakiness + framework compliance checks
.github/scripts/ai-review.mjs	AI API caller that sends diffs to OpenAI for analysis
.github/workflows/ai-pr-review.yml	Full CI workflow: diff extraction, AI review, PR comment, check run, auto-labeling

How It Works

1. PR opened to main — workflow triggers automatically
2. Extracts the git diff (excluding binaries and lockfiles)
3. Sends diff to OpenAI (GPT-4o) for analysis against Playwright + TypeScript best practices
4. AI reviews the diff across 7 categories: flaky patterns, locator usage, assertions, anti-patterns, TypeScript issues, architecture violations, and DRY violations
5. Posts a structured review as a PR comment with severity labels and quality score
6. Creates a check run for branch protection rule compatibility
7. Auto-labels the PR: passed / warning / failed
8. No auto-merge — human approval is always required

Setup Required After Merge

Add an OPENAI_API_KEY secret in repository Settings > Secrets and variables > Actions, then enable the AI PR Review / review check in branch protection rules for main.
