Knowledge Sync — ADO Work Items + ICM Incidents

Reads ADO work items and ICM incidents for the PPBT area, extracts patterns and fixes, and appends them to a persistent knowledge log. Each run only fetches items newer than the last sync — knowledge accumulates over time rather than being overwritten.

Invoke as: /knowledge-sync

Also invoked automatically (inline) by /review, /workitem, and /pac-cli-update when the knowledge base is more than 7 days old. No manual scheduling needed.
