Message Bus Generator

[GenerateMessageBus] emits a MessageBus<TPayload> factory from static channel factory methods marked with [MessageBusRoute].

[GenerateMessageBus(typeof(BusOrderEvent), FactoryName = "Create", BusName = "order-bus")]
public static partial class GeneratedOrderMessageBus
{
    [MessageBusRoute("accepted")]
    private static MessageChannel<BusOrderEvent> Fulfillment()
        => MessageChannel<BusOrderEvent>.Create("fulfillment-orders").Build();
}

The generated factory returns a normal MessageBus<TPayload>, so applications can still call Subscribe for runtime bolt-ons after the generated topology is created.

Diagnostics:

ID	Meaning
`PKBUS001`	The host type must be partial.
`PKBUS002`	At least one `[MessageBusRoute]` method is required.
`PKBUS003`	Route methods must be static, parameterless, and return `MessageChannel<TPayload>`.
