Add enrichInput and enrichOutput DSL functions

[mcruzdev]

This pull request add enrich for inputFrom and enrichedOutput for outputAs methods.

1. outputAs(enrichedOutput

function("task", (Long input) -> input + 5, Long.class)
    .outputAs(enrichOutput((taskOutput, rootInput) -> 
        taskOutput + rootInput.as(Long.class).orElse(0L), Long.class))

2. outputAs(enrichedOutput handling only the root WorkflowModel

.outputAs(
    enrichOutput(rootInput -> {
                                  return rootInput.asNumber().orElseThrow().longValue();
                            })))

3. inputFrom(enriched

                        enrichInput(
                            (lastState, rootInputModel) -> {
                              Long originalInput = rootInputModel.as(Long.class).orElse(0L);
                              return lastState + originalInput;
                            },
                            Long.class)

4. inputFrom(enriched handling only the root WorkflowModel

.inputFrom(
                        enrichInput(rootInput -> rootInput.asNumber().orElseThrow().longValue())))

Closes #1196

[Copilot]

Pull request overview

Adds DSL helpers to simplify enriching inputFrom(...) and outputAs(...) transformations with access to the root workflow input (WorkflowModel), addressing #1196 by reducing boilerplate when reading workflowContext.instanceData().input().

Changes:

• Added FuncDSL.enriched(...) and FuncDSL.enrichedOutput(...) helper functions (including root-input-only variants).
• Introduced EnrichWithModelBiFunction functional interface to support (typedValue, WorkflowModel) enrichment lambdas.
• Added new integration-style tests and updated impl/test Maven dependencies to compile/run them.

Looks good, but please consider renaming to enrich instead and fwiw: https://www.enterpriseintegrationpatterns.com/patterns/messaging/DataEnricher.html

See my comment on the issue, I think the PR needs to be refactor accordingly
