/**
 * The git-sync control plane. Wires the native datasource, the
 * orchestrator (poll + leader-lock), the per-space vault registry, the
 * event-driven listener, and the admin trigger controller.
 *
 * Imports:
 *   - DatabaseModule (global) — PageRepo / SpaceRepo / KyselyDB for the
 *     datasource + orchestrator queries;
 *   - EnvironmentModule (global) — EnvironmentService config;
 *   - CollaborationModule — exports CollaborationGateway for native body writes;
 *   - PageModule — exports PageService for structural mutations;
 *   - ScheduleModule (NOT forRoot) — so SchedulerRegistry is injectable (the
 *     orchestrator registers a DYNAMIC poll interval in onModuleInit). forRoot()
 *     is already registered globally by TelemetryModule; importing the plain
 *     module here avoids a duplicate scheduler registration.
 *
 * RedisService is provided by the global RedisModule (app.module) and CASL's
 * WorkspaceAbilityFactory by the global CaslModule — both resolve without an
 * explicit import here.
