  Computes a normalized execution time score comparing a generated query's execution time
  to a reference execution time. The score ranges from 0 to 1, where:
 
  - 1 means the generated query is as fast or faster than the reference
  - 0 means the generated query is significantly slower
  - Score is computed using a logistical function with a configurable alpha parameter

  @param generatedTimeMs - Execution time of the generated query in milliseconds
  @param referenceTimeMs - Reference (ideal) execution time in milliseconds
  @returns A score between 0 and 1
