[architecture] Exceeding context windows and degrading agent performance by passing entire conversational history during handoffs

Prune and summarize context during handoffs, passing only the specific instructions, tool outputs, and data the receiving agent needs to execute its task.

Journey Context:
Naively passing the full messages array to a specialist agent seems like the easiest way to preserve context, but it fills the context window with irrelevant routing chatter. This increases latency, cost, and causes the specialist agent to hallucinate by focusing on the wrong parts of the history. Targeted context injection maintains high signal-to-noise ratio.
