feat: settlement family complete — village, market, city, port theme packs

Four settlement-kernel themes on village geometry, each 4 motifs:
  village  kinship · harvest · custom · quiet
  market   bargain · weights · crowd · credit
  city     works · rolls · wards · liberties
  port     cargo · passage · tide · wreck

All validate. 11 themes total; index.json rebuilt. Module → 0.5.0.
