fix: clean up dead Temporal operations.go stubs (#31)

- Delete operations.go (TODO stubs, never called by handler.go)
- Refactor handler.go: 8 methods delegate to WorkflowGRPCImpl/SearchAttributesGRPCImpl
- Remove unused query/v1 import
- Remaining inline methods kept (reset, update, activity, namespace, cluster ops)
- No behavior change in API responses

Closes #31
