// event is the AO hook sub-command name installed in qwenManagedHooks
// ("session-start", "user-prompt-submit", "permission-request", "stop"), not
// the native Qwen event name. Qwen Code has no SessionEnd equivalent in the
// adapter yet, so runtime exit still falls back to the reaper.
//
// TODO(qwen): ActivityExited is still runtime-observation-owned. Qwen Code has a
// native SessionEnd hook; if AO installs it, map "session-end" to
// ActivityExited here. Until then, make sure the lifecycle reaper can still mark
// a dead Qwen runtime as exited even when the last hook signal was sticky
// waiting_input.
