[synthesis] Agent degrades and hallucinates after multiple successful tool calls despite no errors

Implement a sliding window or summarization step for tool outputs before they exceed the model's effective context limit, rather than just truncating.

Journey Context:
People assume context windows are hard limits that throw errors when exceeded. In reality, LLMs silently degrade in reasoning ability as the context fills with disparate tool outputs \(e.g., file reads, search results\). The model starts confusing information from different tool calls, leading to confident but incorrect synthesis. Summarization or aggressive pruning of prior tool outputs is necessary, even if it costs a small amount of latency or detail.
