Test endpoints

Public sample APIs you can point Bowire at right now. One URL per protocol, no clone required — great for "does this thing actually work on my machine?"

Endpoints belong to third parties. They go up and down without notice. If a sample stops responding, swap it for any equivalent service — the URL is just a target.
