dotAI AI Auto-Tag Content workflow subaction adding tags

Problem Statement

In the dotAI AI Auto-Tag Content workflow subaction there is a setting, Limit the keywords to pre-existing tags, that when set to True should prevent the workflow from adding additional tags to the system and only tag the piece of content using existing tags. When using this subaction and setting the value of the field to true, the workflow still adds new tags to the system and to the content. It also adds new tags that begin with '['.

So two issues:

1. Setting the Limit keywords setting to True does not prevent the workflow from adding new tags to the system and content.
2. The AI workflow is adding keywords that begin with a '['

Steps to Reproduce

Configure a workflow step to Auto Tag content and set the Limit the keywords to pre-existing tags to True.
Run the workflow on a piece of content
Check the tags in the system and on the content

May need to run it on several pieces of content to get new tags to be created.

Acceptance Criteria

When setting the Limit Keywords to true, the workflow should only add existing tags to the content, it should not create any new tags.

When the workflow is allowed to create new tags (the Limit Keywords setting is set to false), it should not create new tags that start with '['

Start with the dotAI AI Auto-Tag Content workflow subaction and reproduce the behavior using the stated configuration and content workflow steps. Trace how the Limit the keywords to pre-existing tags setting handles tag creation and how generated keywords beginning with '[' are processed. Done means existing tags are applied without creating new ones when enabled, and bracket-prefixed tags are excluded when new tags are allowed.
