/**
 * Wraps a service with debug logging for all method calls.
 *
 * When debug is enabled, creates a Proxy that intercepts all method calls and:
 * - Logs method entry with arguments
 * - Logs method exit with success status and timing
 * - Logs errors when methods throw
 *
 * When debug is disabled (default), returns the original service unchanged
 * with zero overhead.
 *
 * @template T - The service type (must be an object)
 * @param service - The service instance to wrap
 * @param serviceName - Name used in log output (e.g., 'OrgInfoService')
 * @param debug - Whether to enable debug logging (default: false)
 * @returns The service, wrapped with logging if debug=true
 *
 * @example
 * ```typescript
 * // Without logging (production)
 * const service = withServiceDebugLogging(new OrgInfoService(conn), 'OrgInfoService');
 *
 * // With logging (debug mode)
 * const service = withServiceDebugLogging(new OrgInfoService(conn), 'OrgInfoService', true);
 * // Calls will log:
 * // [DEBUG] [SERVICE] OrgInfoService.getOrgIdentity: called → []
 * // [DEBUG] [SERVICE] OrgInfoService.getOrgIdentity: result → success=true duration=150ms
 * ```
