Consolidate Copilot-related and Prompt Engineering Module Update Issues

[rmallorybpc]

Identify and consolidate all open issues related to Copilot modules and prompt engineering (multiple duplicates and related requests, e.g., modules about Copilot usage, prompt engineering, documentation generation). Merge these into a meta-tracking issue, close duplicates, and re-link valid child issues to the new epic. For reporting, provide a count of Copilot/prompt engineering issues linked. Reference the review from 2025-11-13 for known duplicates (see conversation for issue numbers and clustering suggestions).
