Ambassador Generator

[GenerateAmbassador] creates a typed Ambassador<TRequest, TResponse> factory from outbound call, policy, transform, telemetry, and fallback methods.

[GenerateAmbassador(typeof(InventoryAmbassadorRequest), typeof(InventoryAmbassadorResponse), AmbassadorName = "inventory-ambassador")]
public static partial class InventoryAmbassador
{
    [AmbassadorTransform]
    private static InventoryAmbassadorRequest Normalize(InventoryAmbassadorRequest request) => request;

    [AmbassadorCall]
    private static InventoryAmbassadorResponse Call(AmbassadorContext<InventoryAmbassadorRequest> ctx)
        => new(ctx.Request.Sku, "available", "inventory-api");
}

Diagnostics:

• PKAMB001: host type must be partial.
• PKAMB002: exactly one outbound call handler is required.
• PKAMB003: transform, policy, telemetry, call, or fallback signature is invalid.
• PKAMB004: telemetry names must be unique.
