Pull request overview
Adds the Service Activator enterprise integration pattern across the PatternKit stack: a new runtime fluent API (PatternKit.Core), Roslyn source generator + attributes (PatternKit.Generators*), DI-importable production-shaped inventory example (PatternKit.Examples), and accompanying tests/docs/catalog entries.
Changes:
- Introduces
ServiceActivator<TRequest, TResponse>runtime API with a fluent builder and activation result type. - Adds
[GenerateServiceActivator]/[ServiceActivatorHandler]attributes plusServiceActivatorGenerator(with diagnostics + generator tests). - Adds inventory service-activator example, DI registration via
AddPatternKitExamples(), and updates pattern/example catalogs + docs TOCs.
