/**

 * @param {Object} [options]
 * @param {number} [options.minLoopDuration=2.0] - Minimum loop length in seconds
 * @param {number} [options.maxLoopDuration=8.0] - Maximum loop length in seconds
 * @param {number} [options.searchStart=1.0] - Start searching after this many seconds
 * @param {number} [options.searchEnd=0.8] - Search up to this fraction of the track
 * @returns {Object|null} best loop { start, end, duration, score, musicalBonus, totalScore }
 *   or null when no candidate could be scored (callers must handle null —
 *   never invent a result)
