fix(server): turn starts in long threads no longer stall the server#21585

Bind the plan assertion to the final turn-item query.

The test aggregates plans from every traced statement. It also accepts turn_items_recovery_idx. A plan from another lookup, or the older recovery index, can therefore satisfy the assertion without proving that turnItemRows uses turn_items_active_idx.

A long thread with many finished user_message or assistant_message items can still regress to reading its history if the final lookup loses the active index. Filter the traced statements to that lookup and require the active index.

Assert that all seven item lookup plans are captured.

assert.isNotEmpty(itemLookups) requires only one plan. A future edit could remove one lookup while the remaining plans still satisfy this test. Assert the expected count and keep the per-lookup index checks. Turn-item fixtures are not required for this query-plan check.
