feat: Improve multi-term search ranking with co-occurrence boosting and compound matching

Addresses cases where multi-word queries like "search execution from request to shard" return generic single-term matches instead of highly relevant classes matching multiple terms. Applies co-occurrence boosting before truncation to prioritize nodes matching 2+ query terms, adds compound term matching to catch classes like "SearchShardsRequest" that contain multiple query terms at any position, and widens per-term accumulation pools to prevent relevant multi-term matches from being filtered out early.
