*COMPUTE THE PACK POWER PULSES*
===============================

Segments a battery pack power curve into discrete charge/discharge pulses by detecting near-zero crossings. Given a pack power vs. time curve and a zero-proximity ratio, the worker identifies and returns the individual power pulses as a structured dataset. Use this worker when you need to isolate individual power events from a continuous pack power signal for further analysis.

   * - C1-B
     - curve1
     - vector
     - —
     - 
     - Pack power vs. time curve (baseline) to be segmented into pulses; supply a vector of (time, power) pairs — leave empty if the curve is piped directly from an upstream worker.
   * - Zero Ratio
     - zero_ratio
     - scalar
     - 1
     - 
     - Fraction of the curve's full Y-range (Ymax−Ymin) used as the near-zero threshold for pulse boundary detection; dimensionless, range [0, 1], default 0.01 — increase toward 1.0 to treat a wider band around zero as a gap between pulses.
