Overview

Migrate $queryStats tests that live in jstests/noPassthrough/query/queryStats/ (~90 files) into passthrough suites, using per-command query knob overrides instead of cluster-wide setParameter.

Background

Most $queryStats tests are in noPassthrough largely because they set cluster-wide server parameters (internalQueryStatsSampleRate, internalQueryStatsRateLimit, internalQueryStatsWriteCmdSampleRate, internalQueryStatsCacheSize) via setParameter, which leaks state across tests and is incompatible with passthrough suites. As a result, query stats coverage misses the breadth of topologies and behaviors passthrough suites exercise (sharded clusters, stepdowns, BWC, etc.), and new feature tests keep accruing in noPassthrough (e.g. SERVER-97670's query_stats_in_transaction.js).

Depends on SERVER-134528, which makes the sampling knobs settable per-command via runCommand(..., querySettings: {queryKnobs: {...)}}.

Scope of Work* Migrate tests whose only noPassthrough justification is server-parameter state

• Keep genuinely noPassthrough tests (failpoints, node restarts, topology-specific setup) where they are, or split them
• Prefer passthrough suites for new query stats tests going forward

Acceptance Criteria

• Query stats tests that don't require failpoints/restarts run in passthrough suites
• No regression in query stats coverage
