Fix #1280

[Copilot]

Pull request overview

Adds support for treating WorkflowModelCollection results as either a Jackson ArrayNode/JsonNode or as a Java Collection, enabling outputAs(...) lambdas to accept either shape when using listen(..., toOne(...)).

Changes:

• Extend JacksonModelCollection.as(Class<T>) to return this when Collection.class is requested.
• Add a new experimental/test Maven module with a runtime-style test covering outputAs with Collection and with ArrayNode.
• Register the new test module in experimental/pom.xml.

mockito-core is declared as a test dependency here but isn't used by any tests in this module, which adds unnecessary dependency weight and can slow down builds. Please remove it (or add a test that actually needs it).
