Note

Low Risk
Lockfile-only patch upgrade with no app code edits; minor behavioral changes in query parsing are possible but limited to how nested query strings are interpreted.

Overview
Bumps the transitive qs dependency from 6.15.0 to 6.15.2 in yarn.lock only; no application source changes.

The newer patch release fixes parse / stringify edge cases (nested bracket keys, delimiter/charsetSentinel behavior, null/undefined in comma/filter-array modes, and parameterLimit: Infinity with throwOnLimitExceeded). Redis Insight still wires qs.parse as the Express query parser for nested query objects.
