Overview

A one-way, thread-safe cancellation flag shared across a parent agent and the subagents it forks. Fan-out runs each subagent on its own worker thread; when the parent is interrupted the worker threads must learn to stop, but they cannot see the parent's thread-local task epoch. Flipping this flag is the shared signal every subagent polls at its safe checkpoints.
