@onlyworlds/sdk 4.7.1

Changed

• README rewritten: install, a first run against the public demo world (its output shown,
  run as written), your own world with an agent seat for writes, then the reference. It no
  longer calls a world field in a payload an error: the API ignores it.
• Comments, the RFC and pin-file prose no longer name people or internal places.
• Schema repinned v0.30.1-dist.15 → v0.30.2-dist.16 (canonical 00.30.02).
  ONLYWORLDS_VERSION is now '00.30.02'. Field descriptions move with the schema: Location's
  rivalries and partnerships, Marker's order, and Pin's element pair. No field shape and
  no FIELD_SCHEMA entry changed: canonical now requires only name on every type, which is
  what FIELD_SCHEMA already said, so its hand-made exception for the old Pin and Marker
  lists is gone. If the schema lists more than name again, codegen stops and asks for a
  ruling instead of dropping the list. 31/31 file hashes recomputed from the tag.
