- Cache ~/.cache/ms-playwright keyed by Playwright version
- Skip browser download on cache hit, only install system deps
- Applies to both storybook-test and e2e-test jobs
- Reduces CI time by avoiding ~200MB browser downloads

Playwright optimizations:
- Skip install-deps entirely on cache hit (saves ~54s apt operations)
- Only run full install --with-deps on cache miss
- System deps are part of runner image, no need to reinstall

macOS optimizations:
- Cache Homebrew downloads directory (~236 MB)
- Prevents re-downloading native dependencies
- Should reduce setup-cmux time from 100s to ~30-40s

Expected improvements:
- Storybook/E2E tests: 58s → 4s (cache restore only)
- macOS builds: 100s → 30-40s (skip Homebrew downloads)
