Maxim Dolgolyov 09cfaa3bd2 fix(phys8): закрытие критических проблем ревью — миграции, ✓→✓, ConvectionSim 
- Удалены legacy миграции 009/010/015 (создавали несуществующие physics-8-thermal/electro/optics)
- 037_physics_8_hub.sql сделана self-sufficient: INSERT OR IGNORE родителя + UPDATE
- 7 шт. literal ✓ заменены на ✓ в physics_8_lab.html (правило проекта)
- В phys.js добавлен createConvectionSim — главный визуал §4 (тороидальный поток частиц)
  закрытие плана Phase 0 Физики 8
