* compareVersion compares two version strings and returns:

* @param v1 The first version string (e.g., "1.2.3").

* @returns 0 if both versions are equal, 1 if v1 > v2, -1 if v2 > v1.
* @example
* compareVersion("1.2.3", "1.2.4"); // returns -1
* compareVersion("1.2.3", "1.2.3"); // returns 0
* compareVersion("1.2.4", "1.2.3"); // returns 1
