/**
 * Performs a constant-time comparison of two values to prevent timing attacks.
 *
 * This function compares two values (strings, Buffers, or Uint8Arrays) in a way that
 * takes the same amount of time regardless of how many bytes match. This is important
 * for cryptographic operations to prevent timing attacks where an attacker could
 * determine secret values by measuring the time it takes to compare them.
 *
 * **Note:** This implementation is essentially the same as previous constant-time comparison functions (SHA: ***8575fdccff6aa7bedabb638cfb8a7394e0f9e1a4***),
 * using the standard pattern of bitwise operations to ensure timing consistency.
 *
 * **TODO:** Consider reverting this later to roll back to SHA: ***8575fdccff6aa7bedabb638cfb8a7394e0f9e1a4***.
 *
 * @param a - First value to compare
 * @param b - Second value to compare
 * @returns A boolean indicating whether the values are equal
