Finished the versioning changes to the framework to support deletion of agent versions.

https://github.com/BuckRogers1965/AIAgentWorkflow/releases/tag/v2025.08.18.1539

Today's changes were minor, targeted modifications to three files to implement a single feature: version-aware agent deletion.

Here is the breakdown:

1. editor/ui_app_shell.py:

• A new method delete_specific_agent_version was added to handle the deletion logic for a single, specific agent version.
• The old delete_agent method (which deleted all versions of an agent) was identified as orphaned after the UI change.
• The UI code for the old delete button in the agent list was removed from the refresh_agent_list method.

2. editor/ui_editors.py:

• The new "Delete This Agent Version" button was added to the settings tab for ProcEditorFrame and TemplateEditorFrame.

3. editor/workflow_editor.py:

• The new "Delete This Agent Version" button was added to the settings tab for WorkflowEditorFrame.

The result is a more intuitive and safer deletion process that operates from within the context of the specific version being edited, preventing the accidental deletion of agent versions that are in use.
