feat: wire all declared features + error recovery + test coverage (production-ready)

Wired features (previously type-only stubs):
- colorSchemes: page.emulateMedia({ colorScheme }) per capture, tested with
  light vs dark producing different hashes
- devices: DevicePreset → Playwright descriptors (DPR, isMobile, userAgent)
- Parallel capture: Promise.all batches with configurable concurrency
- Per-route timeout: Promise.race with routeTimeout, graceful fallback
- Locales: browser context locale for i18n captures
- Component capture: captureComponents() wired into ci.ts pipeline

Error recovery:
- Gemini retry: 3 attempts with exponential backoff, falls back to
  pixelmatch-only results (no crash)
- Per-route timeout: failed captures return warnings, don't block pipeline
- PR comment: wrapped in try-catch, gh CLI failure is non-fatal
- Each capture job runs in its own browser context — one failure doesn't
  block others

Test coverage:
- discover.ts: 13 tests (framework detection, port detection, route discovery)
- Advanced capture: color schemes, parallel concurrency, timeout handling,
  performance metrics
- 63 tests total, all passing
