Simple CLI wrapper for the CmpStr package to normalize and compare strings directly via terminal

/**
 * @fileoverview
 * Match command for CmpStr CLI.
 *
 * Compares a string or list of strings against a target string and
 * returns similarity scores. Supports sorting, thresholding, and both
 * synchronous and asynchronous processing.
