-- Migration: Inhalte aus chastity_game_set in die normalen Aufgabengruppen-Tabellen übernehmen.
--
-- Jedes chastity_game_set eines Users wird zu einer privaten CHASTITY_ONLY-Aufgabengruppe:
--   aufgaben    (JSON) → aufgabe             + aufgabe_benoetigt_passiv
--   zeitstrafen (JSON) → sperre              + sperre_sperre_fuer
--   finisher    (JSON) → finisher
--
-- Die Prozedur prüft zuerst, ob chastity_game_set existiert – auf leeren Datenbanken
-- ist sie dadurch ein No-op.
