docs: description and Open Graph title on every page and the playground

- camera.NewService and SetAccessibility; AttachWorld wires the accessibility settings
- tests/camera: priorities, blends, cuts, zones, follow, bounds, outputs, shake, zero allocations, BrainStep benchmark
- integration: rewind restores the camera state across a zone change
- camera2d.Adjuster passes the view by value (no per-frame allocation), D304 updated
- modules/camera/module.mk: test-camera in CI, bench-camera
