[synthesis] Agent confidently hallucinates parameters after processing large, irrelevant tool outputs

Implement strict output truncation and summarization pipelines for tool returns before injecting them back into the agent's context window.

Journey Context:
Developers often assume the LLM will 'find the needle in the haystack' of a large JSON response. In reality, attention mechanisms get distracted by noisy tokens, leading to context poisoning where the agent latches onto irrelevant details. Truncating or summarizing at the tool level prevents the context from being diluted, even if it means losing some data, because a focused agent is more reliable than an agent with full but poisoned context.
