Remove Temporal from the architecture in favor of the simpler
transitions + PostgreSQL + Celery approach. This aligns ADR-007
with ADR-010 based on user preference for simpler operations.
Key changes:
- ADR-007 now recommends transitions library instead of Temporal
- Added explicit "Why Not Temporal?" section explaining the trade-off
- Added "Reboot Survival" section documenting durability guarantees
- Updated architecture diagrams and component responsibilities
- Updated ARCHITECTURE.md summary matrix
The simpler approach is more appropriate for Syndarix's scale (10-50
concurrent agents) and uses existing PostgreSQL + Celery infrastructure.

Establishes the hybrid architecture decision:
- LangGraph for agent state machines (MIT, self-hostable)
- Temporal for durable workflow execution (MIT, self-hostable)
- Redis Streams for agent communication (BSD-3, self-hostable)
- LiteLLM for unified LLM access (MIT, self-hostable)
Key decision: Use production-tested open-source components rather than
reinventing the wheel, while maintaining 100% self-hostability with
no mandatory subscriptions.
