      Streaming accumulator that builds the HLL sketch during the analyze collection scan. Modeled on $_internalConstructStats but with constant ~16KB state instead of buffering all values.

      • New accumulator, registered internal-only
      • Implement processInternal() and getValue()
      • Handle null/missing correctly
