Simbiot Harness b60439152b Simbiot Harness v0.1: тактовая лестница на Strands + CQRS/ES-спина
- harness/es.py: append-only event store + проекции (образец — кооп-портал)
- harness/levels.py: уровни 1с/1м/1ч/1д, контекст ∝ масштабу
- harness/scheduler.py: уровневые потоки, идемпотентные тики, absorbed-стабы
- harness/isolated_runner.py + _llm_worker.py: LLM-тик в сабпроцессе
  (глобальный asyncio-рантайм Strands не переживает 2+ create_harness)
- cli.py: init/task/tasks/status/events + requeue (написан самим минутным агентом)
- 9router: отдельный ключ sk-simbiot, модель auto (glm-5.3 первым)
