Optimize repo sync for faster subsequent builds 

- Increase parallel job limit from 10 to 16 (repo sync is network-bound)
- Remove --force-sync from main sync to enable incremental syncs
- Remove --force-sync from date-change sync
- Keep --force-sync only for recovery after sync failure

Expected time savings: 5-10 minutes on subsequent builds.
