Removed: Dockerfile_beefyserver (superseded by the root Dockerfile), sdist/
(upstream release tooling), query.py (broken debug script), raspberrypi3/
(obsolete distro steps and env vars the server now rejects).
systemd and daemontools samples now use COIN=Palladium, the node RPC port 2332,
DB_ENGINE and SERVICES (both required for a working server). HOWTO.rst drops
the Raspberry Pi section.
