Adds clustered primary keys to 7 temp tables to give the optimizer better cardinality and join strategy information: - #hi_plan_stats (plan_id) - #hi_query_stats (query_hash) - #hi_interesting (query_hash) - #hi_primary_window (query_hash) - #hi_query_waits (query_hash) - #hi_query_identifiers (query_hash) - #hi_output (query_hash) Tables without PKs are those with composite keys or multiple rows per hash (staging tables, time_buckets, wait_staging, representative_text). Tested on SQL2022 and SQL2016. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
