feat: add TypeScript strict mode, vitest, zod env validation, playwright, Makefile, .editorconfig
10 improvements to the frontend dev experience:
1. TypeScript strict mode enabled (tsconfig.app.json)
- strict: true, noImplicitAny: true, noUnusedLocals: true
- noUnusedParameters: true, noImplicitReturns: true
- noUncheckedIndexedAccess: true
- Passes with 0 errors
2. Vitest configured with jsdom + @testing-library/react
- vitest.config.ts with coverage provider
- src/test/setup.ts stubs all env vars
- src/App.test.tsx: smoke test (renders without crash)
- 1 test passing
3. .editorconfig added (matches biome: 2-space, lf, 120 cols)
4. Makefile added with standard targets:
make install/dev/build/lint/format/check/typecheck/test/ci/clean
5. Zod env validation (src/lib/env.ts)
- All import.meta.env calls validated via zod schema
- Fails fast with clear error if env vars are invalid
- src/lib/config.ts re-exports from validated env
6. Playwright E2E config + smoke tests
- playwright.config.ts with chromium
- e2e/smoke.spec.ts: homepage + navigation tests
7. CI workflow now blocking on lint + typecheck + test + build
- Removed continue-on-error from lint step
- Added vitest run step
- Added tsc --noEmit step
8. rollup-plugin-visualizer added to vite.config.ts
- Generates dist/stats.html on build
9. Pre-commit hook updated with --staged flag
- Only lints staged files, not entire repo
10. Removed broken .clinerules symlink
Build: 18s, 0 TS errors, 1 test passing, 0 format errors
