The messaging api layer reached around the Waku kernel into the libp2p node (`waku.node.subscriptionManager`, `waku.node.rng`, `waku.node.brokerCtx`). That breaks the declared layering: messaging depends on the Waku *kernel* abstraction, not the raw node. Add a content-topic subscription api on the Waku layer (`waku/api/subscriptions.nim`) and switch the messaging send/subscription paths onto it, plus the kernel's own `rng`/`brokerCtx` fields, so the layer no longer touches `node` internals.
