/**
 * Owns the set of database-upgrade components.
 *
 * Instantiates each upgrade component with the owning coordinator and the
 * shared dependency map, exposes every component through a typed accessor, and
 * re-pushes a refreshed dependency map to all of them when the coordinator's
 * collaborators change (e.g. after a test swaps in a mock DataAccess).
 *
 * This isolates the 18-component instantiation/refresh lifecycle from
 * {@see ABJ_404_Solution_DatabaseUpgradesEtc}, whose remaining job is to be the
 * public upgrade facade. The registry IS the coordinator passed to each
 * component, so components reach their siblings through it. Constructed by the
 * facade only.
