AlexisLeDain 8e415351a0 feat(skills): add react-patterns, react-testing, react-performance ...

Three new skills under skills/ following the SKILL.md convention.

- react-patterns: React 18/19 idioms — hooks discipline, state
  location decision tree, server/client component boundary,
  Suspense + error boundaries, form actions (React 19), data
  fetching matrix, composition recipes, accessibility-first.
- react-testing: React Testing Library + Vitest/Jest, query
  priority order, userEvent, MSW network mocking, axe a11y
  assertions, RTL vs Playwright CT boundary, TDD workflow.
- react-performance: 70-rule performance ruleset adapted from
  Vercel Labs react-best-practices (MIT) across 8 priority
  categories — waterfalls, bundle size, server-side, client
  fetch, re-render, rendering, JS micro, advanced patterns.
  Includes Lighthouse / Web Vitals mapping and attribution to
  upstream.

Cross-links between the three skills and out to frontend-patterns,
accessibility, e2e-testing, tdd-workflow.
