Addresses two new bugbot comments:
1. **Cached terminal data applied incompletely** (#2808048773):
- Problem: Only copied some fields (state, ciStatus, etc.) but omitted title, additions, deletions
- Fix: Added missing fields when applying cached data
2. **Terminal PRs remain permanently unenriched** (#2808048771):
- Problem: Terminal sessions with no cache never got enriched → kept stale defaults forever
- Fix: Removed the "skip enrichment for terminal with no cache" logic
- Behavior: Terminal sessions now enrich at least once (or when cache expires), then skip subsequent enrichments
**Behavior change:**
- Before: Terminal session without cache → skip enrichment forever → stale data
- After: Terminal session without cache → enrich once → cache for 60s → skip while cached
This ensures terminal sessions get accurate PR data at least once, while still avoiding
unnecessary API calls for sessions that already have fresh cached data.
