Review archived workflows 8000/8100 for potential reactivation or deletion

Background

As part of the process code reorganization, the following workflows were archived:

• 8000 (DocIngestion - not used) - formerly 0500
• 8100 (DocUpload - not used) - formerly 0600

These workflows are NOT in the active pipeline. The new 0500 (ConnectorSync) now handles the document ingestion flow with pre-approval filtering.

Action Items

• [ ] Review 8000 (document-ingestion) - determine if any logic should be merged into 0500
• [ ] Review 8100 (document-upload) - confirm deprecated status
• [ ] Decision: Keep archived, merge useful parts, or delete entirely
