Channel Purger Generator

[GenerateChannelPurger] creates a strongly typed factory for ChannelPurger<TPayload>.

[GenerateChannelPurger(
    typeof(InventoryMaintenanceCommand),
    FactoryName = "Create",
    PurgerName = "inventory-maintenance-purger")]
public static partial class GeneratedInventoryChannelPurger;

Generated shape:

public static ChannelPurger<InventoryMaintenanceCommand> Create(
    MessageChannel<InventoryMaintenanceCommand> channel);

The host type must be partial. The generated factory is intentionally small so applications can compose it with container-owned channels, audit sinks, and hosted maintenance services.
