smolcluster eyes AirDrop setup flow

Clever idea, but AirDrop looks like a bootstrap trick rather than a real cluster transport. If smolcluster can turn it into a one-tap pairing flow, that would be a real UX win for hobbyists.

• –Apple’s docs show AirDrop uses BLE plus peer-to-peer Wi-Fi between nearby devices, so it is built for local sharing, not sustained training traffic.
• –That makes it a better fit for discovery, config transfer, or cluster pairing than for moving gradients or activations.
• –The Mac-only constraint is fine for home labs and Mac mini racks, but it won’t advance the project’s broader heterogeneous story.
• –The feature makes most sense as an opt-in bootstrap path, with Tailscale or ordinary networking still the pragmatic default for anything beyond a demo.
