TaskMiddleware class abstract

Signature for middleware that wraps task execution.

Middleware runs before and after every task handler. Use for logging, auth token refresh, analytics, error tracking.

Example:

class LoggingMiddleware extends TaskMiddleware {
  @override
  Future<TaskResult> execute(
    String taskName,
    TaskContext ctx,
    Future<TaskResult> Function() next,
  ) async {
    print('📋 Task started: $taskName');
    try {
      final result = await next();
      print('✅ Task completed: $taskName');
      return result;
    } catch (e) {
      print('❌ Task failed: $taskName - $e');
      rethrow;
    }
  }
}

// Register
