jif 9dd22890f5 Add an LRU baseline to skill shadow selection (#38197)
## What changed

- Track the 50 most recently invoked skills for each thread and evaluate them
  as the `lru_v1` shadow-selection method.
- Filter stale and duplicate entries while preserving recency order.
- Increase the shadow result limit to 50 and add a `21_50` rank bucket.

## Testing

- Add unit coverage for recency refresh, eviction, filtering, limits, and rank
  buckets.
- Add an extension test showing that `lru_v1` recovers a skill invoked on an
  earlier turn.
