Module cqrs 

Generic CQRS commands, queries, and their handlers.

Generated code emits type aliases only — zero logic per entity:

// Generated (replaces ~200 lines per entity):
pub type CreateOrderCommand  = GenericCreateCommand<Order, CreateOrderDto>;
pub type UpdateOrderCommand  = GenericUpdateCommand<Order, UpdateOrderDto>;
pub type DeleteOrderCommand  = GenericDeleteCommand<Order>;
pub type GetOrderQuery       = GenericGetQuery<Order>;
pub type ListOrderQuery      = GenericListQuery<Order, OrderFilters>;

pub type OrderCommandHandler = GenericCommandHandler<Order, CreateOrderDto, UpdateOrderDto, OrderService>;
pub type OrderQueryHandler   = GenericQueryHandler<Order, OrderFilters, OrderService>;

Custom command/query types (beyond CRUD) live in the // <<< CUSTOM zone and implement the standard Command / Query traits from command.rs / query.rs.
