 * Returns true when `entry` is a parent-owned background ACP session AND the

 * strictly narrower check than {@link isParentOwnedBackgroundAcpSession}: the
 * target must match *and* the caller must be the parent.
 *
 * Used to gate behaviors that only make sense for the parent↔own-child pair
 * (e.g. skipping the A2A ping-pong flow in `sessions_send`), so that an
 * unrelated session with broad visibility (e.g. `tools.sessions.visibility=all`)
 * sending to the same target is still routed through the normal A2A path.
