- ModuleRegistryService with findAll, findBySlug, findActiveForTenant, activate/deactivate, seedModule
- ModuleRegistryController with GET /modules, GET /modules/active, POST activate/deactivate
- ModuleGuard + @UseModule() decorator for tenant-scoped module access control
- ActivateModuleDto with UUID validation
- Registered ModuleRegistryModule in AppModule imports
