Report #46691

[frontier] When parent agent tasks are cancelled or modified, child agents continue executing orphaned sub-tasks, wasting resources and causing side effects

Implement hierarchical cancellation tokens that propagate through agent spawn trees; when a parent is cancelled, all descendants receive the signal and can gracefully abort or checkpoint

Journey Context:
In distributed systems, this is standard. In agent frameworks, it's often missing. Without it, changing a high-level goal leaves zombie agents running. The fix requires passing cancellation context through handoffs \(like in Swarm\) and checking it before tool use.
