// event is the AO hook sub-command name installed in kiroManagedHooks
// ("session-start", "user-prompt-submit", "permission-request", "stop"), not
// the native Kiro event name (agentSpawn/userPromptSubmit/preToolUse/stop).
// Kiro currently has no session/process-end hook in the adapter, so runtime
// exit still falls back to the lifecycle reaper.
//
// TODO(kiro): ActivityExited is still runtime-observation-owned. If Kiro adds a
// native session/process-end hook, map that hook to ActivityExited here. Until
// then, make sure the lifecycle reaper can still mark a dead Kiro runtime as
// exited even when the last hook signal was sticky waiting_input.
