 Many modules have happy-path tests but lack coverage for:

 ## Context
-Currently, the Timmy agent (`src/timmy/agent.py`) uses `src/timmy/backends.py` which provides a simple abstraction over Ollama and AirLLM. However, this lacks:
 - Automatic failover between multiple LLM providers
 - Circuit breaker pattern for failing providers
 - Cost and latency tracking per provider
