[synthesis] Agent loops derail silently due to accumulated tool output noise rather than explicit errors

Implement a 'context distillation' step before each planning phase, summarizing previous tool outputs into a structured state representation instead of appending raw outputs to the context window.

Journey Context:
Developers often increase context window limits to handle long agentic loops, assuming the model can attend to the original goal amidst growing tool output. However, as raw JSON/text outputs accumulate, the attention mechanism degrades, causing the agent to focus on recent, irrelevant tool artifacts \(like a stray log line\) rather than the original objective. This doesn't throw an error; the agent just silently shifts its goal. Simply truncating history loses state. Distilling state preserves signal while shedding noise.
