Nikhil Sonti 3d4e493512 feat(eval): add showcase dataset generator with before/after screenshots

Standalone script that runs the BrowserOS agent on tasks and captures
rich execution traces for website showcase galleries:

- Before/after screenshots per tool call via AI SDK callbacks
- CSS crosshair overlays injected via browser.evaluate() for
  element-targeting tools (click, fill, hover, etc.)
- Accessibility snapshot capture at each step
- Per-task JSON manifests with execution metadata
- R2 upload with URL rewriting for cloud-hosted galleries

New files:
- apps/eval/scripts/showcase/ (generate, executor, crosshair,
  manifest, uploader, types)
- apps/eval/.env.example (R2 credentials template)

Also adds Browser.getElementCenter() public method for coordinate
resolution without triggering actions.
