[agent\_craft] Sub-agents fail because they receive full parent context history

When delegating to a sub-agent, pass only a structured 'task brief' \(goal, constraints, specific inputs\) rather than the parent's entire conversation history. Return only a structured 'result brief' to the parent.

Journey Context:
In multi-agent systems, it's tempting to pass the full conversation history to a sub-agent so it 'knows everything'. This causes context explosion and cross-talk: the sub-agent gets confused by irrelevant parent context \(like user pleasantries or failed previous attempts\). The alternative is isolated execution. By passing a strict task brief, the sub-agent operates in a clean, focused context window. The tradeoff is that the sub-agent might lack implicit context, but this is easily fixed by requiring the parent to explicitly include necessary paths/variables in the brief, forcing clean interfaces between agents.
