feat(pipeline): route simple queries through reader thread (Option B)
    
    Remove pause/unpause mechanism from PipelineReaderThread and instead
    route simple protocol queries through the pipeline via new
    executeSimplePipeline() and executeBatchSimplePipeline() methods.
    
    Key changes:
    - Remove pause()/unpause() and associated polling logic from reader thread
    - Add executeSimplePipeline() that sends 'Q' messages and waits on a
      ResponseSlot for the reader thread to deliver results
    - Add executeBatchSimplePipeline() for batch simple query execution
    - Fix slot ordering: add slots to pending queue before flush/sync to
      prevent race where reader processes response before slot exists
