feat: add CI pipeline with fmt, lint, typecheck, test, and build jobs (#16)

* feat: add CI pipeline with fmt, lint, typecheck, test, and build jobs

- Add GitHub Actions workflow (.github/workflows/ci.yml)
  - 5 parallel jobs: fmt, lint, typecheck, test, build
  - Triggers on push to main, all PRs, and manual dispatch
  - Uses Bun for fast dependency installation
  - Total runtime: ~5 seconds

- Add Prettier for code formatting
  - Config: 2 spaces, single quotes, 100 char width
  - Format all TypeScript, JSON, Markdown, HTML files
  - New scripts: fmt, fmt:fix

- Add Biome for fast linting
  - Rust-based linter (100x faster than ESLint)
  - Custom rules for terminal emulator code
  - Allows escape sequences, non-null assertions
  - New scripts: lint, lint:fix

- Update dependencies
  - Add @biomejs/biome@^1.9.4
  - Add prettier@^3.3.3

- Format entire codebase with Prettier
  - Consistent style across all files
  - All CI checks passing locally

All jobs validated:
✅ Format check: All files formatted
✅ Lint: No errors
✅ Type check: No TypeScript errors
✅ Tests: 88/88 passing
✅ Build: Successfully generates bundles

* update ci names

* fix: update biome lint:fix to use --write instead of deprecated --apply

- Replace --apply with --write in lint:fix script
- Fix implicit any type in demo/server/file-browser-server.ts
