Root README and documentation README: daemon + Docker/Nix status.
Roadmap: daemon checked off, real overlay peering stays open.
pilot.md: docker/nix and sn-node daemon mentioned as the comfortable
path beside the manual steps. AGENTS.md server status line updated.
pilot.md: step-by-step for connecting two households (link-agnostic),
measurement protocol M0-M4 (link baseline, uplink baseline, pooled,
concurrent downloads, sn-fair Soll/Ist comparison), safety/legal
