 * Create a customized fetch function with optional features.

 * This function composes multiple fetch wrappers in the following order:
 * 1. Timeout wrapper (if timeoutMs is specified)
 * 2. Header stripping wrapper (if stripHeaders is specified)
 * 3. Progress tracking wrapper (if enableProgressLog or progressCallback is specified)
 *
 * @param params - Configuration parameters for fetch customization
 * @returns Customized fetch function, or undefined to use default fetch
 *
 * @example Basic usage with timeout
 * ```typescript
 * const customFetch = createClientFetch({
 *   logger: myLogger,
 *   enableProgressLog: false,
 *   progressCallback: undefined,
 *   timeoutMs: 30000,
 *   providedFetch: undefined,
 * });
 * ```
 *
 * @example With progress tracking
 * ```typescript
 * const customFetch = createClientFetch({
 *   logger: myLogger,
 *   enableProgressLog: true,
 *   progressCallback: (event) => {
 *     if (event.type === 'download-progress') {
 *       console.log(`Progress: ${event.percentage}%`);
 *     }
 *   },
 *   timeoutMs: undefined,
 *   providedFetch: undefined,
