[synthesis] Multi-agent systems degrade as orchestrator context fills with subagent metadata

Strip conversational metadata and summarize subagent outputs before injecting them back into the orchestrator's context window; monitor the orchestrator's task-token to meta-token ratio.

Journey Context:
In multi-agent frameworks, subagents often return verbose logs or conversational filler \('I am thinking...', 'Here is the result...'\). Over multiple turns, the orchestrator's context window fills with this meta-talk, pushing out the original system prompt or critical task details. The agent doesn't error out; it just loses focus and starts giving generic answers because its attention is dominated by procedural metadata. Standard token count alerts don't catch this; you must measure the ratio of actual task data versus conversational scaffolding.
