/**
 * Calculate Portfolio Rebalancing
 *
 * Portfolio rebalancing is the process of bringing portfolio weights back to their
 * target allocations. This can be done through proportional scaling or fixed rebalancing.
 *
 * Methods:
 * - Proportional: Scale all weights proportionally while maintaining relative ratios
 * - Fixed: Rebalance to exact target weights
 *
 * @param options - Current weights, target weights, portfolio value, and rebalancing parameters
 * @returns Rebalancing result with trade amounts and costs
 *
 * @example
 * ```typescript
 * // Fixed rebalancing to target weights
 * const rebalancing = calculatePortfolioRebalancing({
 *   currentWeights: [0.6, 0.4],
 *   targetWeights: [0.5, 0.5],
 *   portfolioValue: 100000,
 *   method: 'fixed'
 * });
 *
 * // Proportional rebalancing with transaction costs
 * const proportionalRebalancing = calculatePortfolioRebalancing({
 *   currentWeights: [0.55, 0.45],
 *   targetWeights: [0.5, 0.5],
 *   portfolioValue: 100000,
 *   method: 'proportional',
 *   transactionCosts: 0.001, // 0.1%
 *   includeTransactionCosts: true
 * });
 * ```
