/**
 * Calculate IRR using Bisection method (robust fallback)
 *
 * Bisection is a robust root-finding method that guarantees convergence
 * if a sign change exists in the interval. It's slower than Newton-Raphson
 * but more stable for difficult cases.
 *
 * @param cashFlows - Array of cash flows
 * @param timePeriods - Array of time periods in years
 * @param maxIterations - Maximum number of iterations
 * @param tolerance - Convergence tolerance
 * @returns IRR result with rate, iterations, and method used
 * @throws Error if no sign change found in reasonable interval
