Roll back junction-contact / discharge / light-theme simulation changes
to the previously stable production tree while keeping linear history.

Unify CAD conveyor on / and /details, add RealSense D435i + contact paddle
physics, keep items moving through scan, lock 7×10 drop validation, and
ship Stage 2 artifacts with production on :3100 (permanent HTTPS still blocked).

Add physicalItemMotion as the single source of item pose, synchronize belt/item speed at 1 m/s, route items through chutes, keep C/D items settled inside roll-cages, render historical settled items, and use STL models with explicit fallbacks.
- Add continuousPlayback.ts with phase-based state machine
- Add conveyorPath.ts for physics-accurate item positioning (1m=1unit, 1m/s)
- Create SorterDigitalTwinContinuous.tsx for main page 3D scene
- Update MainPage to use ContinuousPlaybackState
- Add 16 unit tests for playback logic
- Add Playwright test script for browser QA
- Screenshots: case1_start, case1_detection, case1_routing, case2_started, case8_or_finished
Timeline per case: ~6.3s (spawn → detection → classification → routing → exit)
Total playback: ~50s for all 8 cases
