Add summary to side effect and mutable side effect.

closes #2702

---

Note

Adds options to set a summary on side effects/mutable side effects and plumbs this metadata through APIs and state machines to be recorded on history markers.

• Workflow API:
  • Add SideEffectOptions and MutableSideEffectOptions with summary.
  • New overloads: Workflow.sideEffect(.., SideEffectOptions) and Workflow.mutableSideEffect(.., MutableSideEffectOptions) (and type-aware variants).
  • Extend WorkflowOutboundCallsInterceptor (+ base) with overloads for side/mutable side effects.
• Replay/Sync Contexts:
  • ReplayWorkflowContext.sideEffect/mutableSideEffect signatures accept UserMetadata.
  • SyncWorkflowContext builds UserMetadata from options and passes it through.
• State Machines:
  • SideEffectStateMachine and MutableSideEffectStateMachine attach UserMetadata to record-marker commands.
  • StateMachineCommandUtils.createRecordMarker accepts optional UserMetadata.
• Misc/Tests:
  • Update WorkflowInternal, tracing interceptor, dummy/testing contexts to support new overloads.
  • Add HistoryUtils.assertEventMetadata; update tests to assert metadata on side effect, mutable side effect, activities, local activities, child workflows, timers, and Nexus operations.
