data(economics): address PR #147 review — fused/activity pin fixes

Review fixes for the #1016 cultural pass (Hoshe/Paula/Miri):

- Kruger 60 (GJ 860A) xhosa -> cosmopolitan (Miri): GTTR describes an
  Afrikaner/Xhosa/Zulu founding "without mapping cleanly onto any of
  them" — the textbook genuinely-fused case, which taxonomy rule 4
  resolves to cosmopolitan rather than one of the three. Commented.
- Altmark (GJ 357) financial_technocratic -> cosmopolitan (Paula):
  reverts to the original shipped value; the GTTR reads as commercial
  non-alignment, not credential-based technocracy.
- Kampala Gate (GJ 667B) + Moyale (GJ 1292) keep swahili but add inline
  comments documenting that these are East-African-INTERIOR founders
  (Baganda; Kenyan/Ethiopian Borana-Oromo) for which the taxonomy has no
  dedicated token — swahili is the nearest available, NULL would fall to
  the wrong corridor default. Gap logged for a follow-up taxonomy value.
  Mwangaza (693) swahili is literally correct (coastal) — untouched.
- heritage-taxonomy-draft.md: stale "(38)" subheadings -> "(47)" to match
  the actual canonical count (Hoshe/Miri doc typo).

Retracted: Pedra Seca (GJ 421B) xhosa — reviewer thought it lacked
authored backing, but its gttr.md explicitly states "Afrikaans and Xhosa
heritage"; pin kept.
