      removeInclusionProjectionBelowGroupRecursive (planner_analysis.cpp) only matches STAGE_GROUP, so it skips StreamingGroupNode (STAGE_STREAMING_GROUP) and eligible fetch plans keep a redundant projection below the group. Found by Copilot in review of SERVER-138655.

      • Handle both stage types.
      • Add a streaming-enabled variant of StreamingGroupEligibilityTest.InclusionProjectionBelowEligibleGroupIsElided.
