feat(viewer,ui04): E03 continuous scroll engine — pure state machine, rAF orchestration, boundary continuity
- stream.ts: advanceStream (per-frame, dt cap 50ms), loop generation keys, window math (DOM<=16, queue<=30, 480px buffer), anchorRebuild (photo-position preserving), removePhoto, single-photo static
- useVerticalPhotoStream: rAF integration, direct transform writes (no per-frame Vue reactivity), low-frequency item sync, ResizeObserver re-anchor, stepForTest hook
- EmbedStream wired to engine; cycle copies aria-hidden; img error -> controlled drop
- tests: 14 unit cases (236 viewer total), e2e: 32px/2s speed, boundary continuity <2.5px, DOM<=16 over 20s, 32s recording with loop boundaries
