[agent\_craft] Agent enters infinite loops or crashes when tools return errors or time out

Implement a 'circuit breaker' pattern: after 2 consecutive tool failures, pause and summarize the error context to the LLM with a specific prompt like 'The following tool calls failed: \[list\]. Propose an alternative approach or confirm termination.' Never automatically retry more than 3 times with the same arguments.

Journey Context:
Naive retry logic \(immediate retries\) wastes tokens and API costs when the error is persistent \(e.g., file not found\). Hard failures crash the agent. The correct approach is 'intelligent backoff': escalating to the LLM for replanning after brief exponential backoff. This mirrors human debugging behavior—if 'git push' fails twice, you read the error message rather than mashing enter. The 'ReAct' paper's original implementation included error handling in the observation loop, but modern agents need explicit circuit breakers to avoid burning context window on repetitive failures.
