Please help me complete the query (Query) service business code for the `System Platform` object.

### Standard Query Example (Reference)
```go
import (
	"github.com/teaql/teaql-golang/core"
	"github.com/teaql/teaql-golang/runtime"
	. "crm-erp-service-core-workspace-go/lib"
	"crm-erp-service-core-workspace-go/lib/platform"
)

func QueryExample(ctx *runtime.UserContext) (*core.SmartList[*platform.Platform], error) {
	// Query list
	listResult, err := Q.PlatformsMinimal().
		// WithIdIs(/* val */).
		// WithNameIs(/* val */).
		// WithCreateTimeIs(/* val */).
		// WithLastUpdateTimeIs(/* val */).
		// WithVersionIs(/* val */).

		Comment("what: Retrieve entities based on filters").
		Purpose("why: Retrieve entities").
		ExecuteForList(ctx)

	if err != nil {
		return nil, err
	}

	return listResult, nil
}
```

### Your Task
Please implement the real query logic for `System Platform` based on my specific business needs.
