Phase 10/11 WIP — pool + motion-mode + 8×8 templates (rolled back)

Объединённое состояние работ:
  - Phase 10: source pool, motion-driven layout, Frigate motion_pulse,
    zone-filter в pool, --source / --motion-mode CLI
  - Phase 11 Steps 1-3c: 8×8 микро-сетка, JSON templates с asymmetric
    layouts (tpl_1/3/4/5/6/7/8), reload через ZMQ, auto-labels per camera

В прод отдеплоено и откачено: используем gx/cuframes-composer:0.10 как
baseline. Phase 11 продолжится в branch phase11b-cpp как C++ refactor
с ООП-моделью Cell/Layout/Decoration.
