[dotnet-port-fixes] Add workflow checkpoint identity regression coverage

[github-actions]

Summary

Add Go regression coverage for checkpointed workflow-as-agent sessions so we keep parity with the .NET guidance around stable hosted-agent identities.

The new workflow/agentworkflow tests prove three cases:

1. Reconstructing the outer workflow agent resumes correctly when the hosted inner agent keeps the same agent.Config.ID and agent.Config.Name.
2. Reconstructing with a fresh random inner agent ID fails checkpoint compatibility.
3. Reconstructing with the same inner agent ID but a different name also fails compatibility, because the hosted executor identity includes both values.

The updated workflow samples now document that requirement and assign stable IDs in the workflow-as-agent examples so checkpointed sessions remain resumable when the workflow is rebuilt.

Breaking Changes

No.

Tests and Examples

• go test ./workflow/agentworkflow -run 'TestNew_(WorkflowAgentSession|SerializedSessionResumes)'
• go test ./examples/03-workflows/checkpoint/checkpoint_and_rehydrate ./examples/03-workflows/agents/workflow_as_an_agent ./examples/03-workflows/observability/workflow_as_an_agent
• Updated examples:
  • examples/03-workflows/checkpoint/checkpoint_and_rehydrate/main.go
  • examples/03-workflows/agents/workflow_as_an_agent/main.go
  • examples/03-workflows/observability/workflow_as_an_agent/main.go

Notes

The upstream .NET change was test/sample guidance rather than a runtime code change, and the Go port follows the same scope: regression coverage plus sample guidance, with no exported API changes.
