Add test suite for React portfolio app

Summary

Install Vitest + Testing Library, fix missing react-router-dom dependency, and add component rendering + routing tests for all 5 page components. When complete, npm test runs a green suite covering all routes and components.

Changes

• Test infrastructure — Install vitest, @testing-library/react, @testing-library/jest-dom, @testing-library/user-event, jsdom, react-router-dom (missing explicit dep). Create vitest.config.ts with jsdom environment, src/test/setup.ts importing jest-dom matchers. Add "test": "vitest run" to package.json scripts. Files: package.json, vitest.config.ts, src/test/setup.ts, tsconfig.app.json (add test include)
• App router tests — Verify all 4 routes (/, /intouch, /pillthought, /palkia) render correct components. Test that unknown paths don't crash. File: src/__tests__/App.test.tsx
• Home page tests — Smoke render, verify project cards grid renders all items, social icons row renders links, navigation callbacks fire on card clicks, footer renders. File: src/__tests__/Home.test.tsx
• Intouch page tests — Smoke render, skills list renders expected items, external link elements present, image error handler fallback works. File: src/__tests__/Intouch.test.tsx
• PillThought page tests — Smoke render, section headings render (Origins, Achievements, Future), media elements present, navigation links render. File: src/__tests__/PillThought.test.tsx
• Palkia page tests — Smoke render, Section/ImageBlock/FooterBar sub-components render correctly, all content sections present. File: src/__tests__/Palkia.test.tsx
• Lint cleanup — Fix the 1 ESLint error in Palkia.tsx (missing react/jsx-no-target-blank or similar) and remove unused eslint-disable directives across all files

Verification

• Build: cd my-portfolio && npm run build
• Test: cd my-portfolio && npx vitest run
• Lint: cd my-portfolio && npx eslint . (0 errors)
• Key behaviors: all 4 routes render, all components mount without errors, test suite exits 0
