feat: add playwright-pro plugin — production-grade Playwright testing toolkit (#254)

Complete Claude Code plugin with:
- 9 skills (/pw:init, generate, review, fix, migrate, coverage, testrail, browserstack, report)
- 3 specialized agents (test-architect, test-debugger, migration-planner)
- 55 test case templates across 11 categories (auth, CRUD, checkout, search, forms, dashboard, settings, onboarding, notifications, API, accessibility)
- TestRail MCP server (TypeScript) — 8 tools for bidirectional sync
- BrowserStack MCP server (TypeScript) — 7 tools for cross-browser testing
- Smart hooks (auto-validate tests, auto-detect Playwright projects)
- 6 curated reference docs (golden rules, locators, assertions, fixtures, pitfalls, flaky tests)
- Leverages Claude Code built-ins (/batch, /debug, Explore subagent)
- Zero-config for core features; TestRail/BrowserStack via env vars
- Both TypeScript and JavaScript support throughout
