ZenQueryClient class

Client for managing query configuration and cache.

Inspired by TanStack Query's QueryClient pattern, this provides a centralized place to configure default options for all queries.

Usage

// Create client with default options
final queryClient = ZenQueryClient(
  defaultOptions: ZenQueryClientOptions(
    queries: ZenQueryConfig(
      staleTime: Duration.zero,
      retryCount: 1,
    ),
  ),
);

// Register with Zen DI
Zen.put(queryClient);

// Queries automatically use these defaults
final query = ZenQuery(
  queryKey: 'users',
  fetcher: (token) => api.getUsers(),
);
