An update plugin step with no filtering attributes

Update plugin step fires on every column change.

No filtering attributes means the step runs on every update of every column, which autosave multiplies, spending compute and feeding re-trigger loops. Microsoft's guidance calls for filters on every Update step.

In the Plugin Registration Tool, check the filtering attributes on every step registered on Update. An empty list means it fires on every column change on the row, which autosave then multiplies.

Register filtering attributes for only the columns the step reacts to.

This one is environment health, so it carries a plain label and no control mapping. Presenting an operational gap as a security finding would make the real security findings harder to trust, so we keep the two apart.

• A plugin step that re-triggers itself on every save
• Two plugin steps at the same execution order writing one column
• A plugin registered twice on the same message
• A plugin step on Retrieve or RetrieveMultiple
