/**
 * Calculate improved initial guess for IRR calculation
 *
 * Uses a simple approximation based on total cash flows to provide
 * a better starting point than a fixed value, which can improve
 * convergence speed and stability.
 *
 * @param cashFlows - Array of cash flows (positive for inflows, negative for outflows)
 * @returns Initial guess for discount rate (as decimal)
