[frontier] Monolithic agent conversations hit context limits and accumulate compounding errors

Spawn ephemeral agent instances for each distinct subtask with a focused, minimal context window. Collect the structured result, destroy the instance, and integrate the result into the parent agent's context.

Journey Context:
A single long-running agent conversation accumulates problems: context bloat \(every tool output stays in context\), error compounding \(one mistake poisons all subsequent reasoning\), and goal drift \(the agent loses sight of the original task as context grows\). Ephemeral spawning inverts this: the parent agent decomposes the task, spawns a child agent with only the context needed for its subtask, collects a structured result, and discards the child. The child never sees irrelevant context, so it reasons more cleanly. The parent never sees the child's intermediate steps, so its context stays lean. This is more expensive in LLM calls but dramatically more reliable for complex multi-step tasks. OpenAI Swarm implements this pattern natively—each handoff can be viewed as spawning an ephemeral agent context.
