Before relaying a trampoline payment, we check if the next node is one of our direct peers. If that's the case, we check their features to see if they support waking up through notifications, in which case we go through the wake-up flow. Note that we don't need this for channel relay, because: - if it is a Bolt 12 payment, the recipient will use a `wallet_node_id` to let us know that they support wake-up notifications - if it is a Bolt 11 payment, we use a custom `short_channel_id` for phoenix that also lets us know that they support wake-up notifications
