Report #21179

[frontier] Sub-agents lacking permissions or context to complete delegated tasks

Pass scoped capability tokens and minimal required context \(not the whole history\) to sub-agents.

Journey Context:
When an orchestrator delegates to a worker, passing the entire chat history is a security risk and wastes context. Passing too little means the worker fails. The pattern is to synthesize a task brief \(the specific goal plus necessary context\) and a capability token \(a scoped auth token that only allows the tools needed for that task, e.g., read-only file access\). This enforces least privilege and optimizes context usage.
