Minor Changes

• #23084 3007515 - #added Add Telemetry.MetricCardinalityLimit config to support limiting Beholder OTel SDK metric cardinality.

• #23136 aa67b6b - #added The v2 workflow engine now emits ClassifiedExecutionStatus on WorkflowExecutionFinished events, distinguishing failures caused by the user's workflow (USER_ERROR) from platform/infrastructure failures (SYSTEM_ERROR). The v1 engine is unaffected.

• #23134 46a0f6e - Minor bump to start next version

Patch Changes

• #22708 db2daaa - #bugfix Rebuild the in-memory workflow execution store's map when pruning so old bucket storage becomes eligible for GC. Go maps never shrink after deletes, which stranded memory as the store churned through millions of executions.
