// defaultSubagentTimeout bounds one sub-agent's whole run. DevDocs/design/05-子代理.md
// §7 requires a timeout and an anti-runaway bound; the scheduler already
// implements both (PerAgentTimeout, Abort/CancelAll), so production must supply a
// value or the per-agent timeout stays inert (the scheduler's zero means "no
// timeout"). The number is deliberately generous — a sub-agent runs up to 8 tool
// rounds like any loop — and is a single knob to revisit when design/05 fixes a
// concrete figure.
const defaultSubagentTimeout = 10 * time.Minute

// wireSubagentTool registers the sub-agent dispatch tool with the dispatcher, so
// the agent can finally reach the orchestration layer at runtime (before this,
// (*orchestration.Scheduler).Spawn had no production caller and design/05 was
// library-only).
//
// The capability is registered with its default reachability markers (both
// false), which keeps it owner-only: the design/11 §3 policy engine hides the
// schema from a group/stranger session and the loop's security gate rejects the
// call there. Design/05 §6/§7 give no group/stranger allowance for spawning
// background agents, and being able to spawn one is a heavy operation, so the
// safe default is chosen deliberately rather than enabled by accident.
