Feature workflow history propagation

[cicoyle]

Add workflow history propagation example highlighting usage:

  // Propagate full lineage chain (ancestor + own history)                                                                               
  workflow.WithHistoryPropagation(workflow.PropagateLineage())                                                                           
                                                                                                                                         
  // Trust boundary — only own history, no ancestors                                                                                     
  workflow.WithHistoryPropagation(workflow.PropagateOwnHistory())  

consumption:

	history := ctx.GetPropagatedHistory()

	merchantWf, err := history.GetLastWorkflowByName("MerchantCheckout")
	if err != nil {
		return FraudCheckResult{}, fmt.Errorf("expected MerchantCheckout in propagated history: %w", err)
	}
	processPaymentWf, err := history.GetLastWorkflowByName("ProcessPayment")
	if err != nil {
		return FraudCheckResult{}, fmt.Errorf("expected ProcessPayment in propagated history: %w", err)
	}
	merchant, err := merchantWf.GetLastActivityByName("ValidateMerchant")
	if err != nil {
		return FraudCheckResult{}, fmt.Errorf("expected ValidateMerchant in propagated history: %w", err)
	}
	card, err := processPaymentWf.GetLastActivityByName("ValidateCard")
	if err != nil {
		return FraudCheckResult{}, fmt.Errorf("expected ValidateCard in propagated history: %w", err)
	}
	spending, err := processPaymentWf.GetLastActivityByName("CheckSpendingLimits")
	if err != nil {
		return FraudCheckResult{}, fmt.Errorf("expected CheckSpendingLimits in propagated history: %w", err)
	}

Future extension ideas:

workflow.WithHistoryPropagation(                                                                                                       
      workflow.PropagateLineage(),                                                                                                       
      workflow.WithMaxDepth(3),                         
      workflow.WithRedactInputs(),

Pull request overview

Adds a new end-to-end example demonstrating Dapr Workflow history propagation (lineage vs own-history) and updates Go module dependencies to support the feature set.

Changes:

• Bump Go module deps (notably github.com/dapr/kit and github.com/golang/mock) in root go.mod/go.sum.
• Add a new examples/workflow-history-propagation example app showing propagation across parent/child workflows and activities.
• Add supporting README, local (standalone) Dapr component config, and Kubernetes manifests + Dockerfile for running the example.
