Message Expiration Generator

[GenerateMessageExpiration] emits a typed factory for MessageExpiration<TPayload>.

[GenerateMessageExpiration(
    typeof(OrderCommand),
    FactoryName = "Create",
    PolicyName = "order-message-expiration",
    HeaderName = "x-order-expires-at",
    DefaultTtlMilliseconds = 1200000,
    ExpiredReason = "Order command expired before fulfillment accepted it.")]
public static partial class GeneratedOrderMessageExpiration;

The generated route is useful when expiration metadata is part of a stable messaging contract. It keeps policy names, header names, TTLs, and rejection reasons declared once and benchmarkable.
