[synthesis] Agent loops on file not found despite reading directory contents successfully

Instruct the agent to use exact string matching from ls or grep output in subsequent commands, or disable summarization for stderr outputs entirely.

Journey Context:
Agents often truncate or summarize long tool outputs to save context. When an error occurs, the summarizer might drop the specific casing or path that caused the failure. The agent then hallucinates a path based on its internal \(incorrect\) representation, leading to repeated failures. The synthesis is that context window management \(summarization\) directly causes context poisoning \(loss of ground truth\), creating an invisible derailment where the agent cannot see its own mistake because the system optimized it away.
