/**
 * Custom hook that manages a timeout with automatic cleanup.
 * Provides a reliable way to handle timeouts that are properly cleaned up
 * on component unmount or when dependencies change.
 *
 * @param callback - The function to execute after the delay
 * @param delay - The delay in milliseconds (null to clear the timeout)
 * @param deps - Optional dependency array. If provided, timeout restarts when deps change.
 *               If not provided, callback updates via ref without restarting timeout.
 *
 * @example
 * ```tsx
 * // Runs once, callback updates via ref
 * useTimeout(() => {
 *   console.log('This runs after 1 second')
 * }, 1000)
 *
 * // Restarts timeout when count changes
 * useTimeout(() => {
 *   console.log('Count:', count)
 * }, 1000, [count])
 * ```
