   * The {@code com.alibaba.cloud.ai.graph} package provides classes and interfaces for
   * building stateful, multi-agent applications with LLMs. It includes core components such
   * as {@link com.alibaba.cloud.ai.graph.StateGraph},
   * {@link com.alibaba.cloud.ai.graph.CompiledGraph},
   * {@link com.alibaba.cloud.ai.graph.internal.node.Node}, and
   * {@link com.alibaba.cloud.ai.graph.internal.edge.Edge}, which facilitate the creation
   * and management of state graphs.
   *
   * <p>
   * Key classes and interfaces:
   * </p>
   * <ul>
   * <li>{@link com.alibaba.cloud.ai.graph.StateGraph} - Represents a state graph with nodes
   * and edges.</li>
   * <li>{@link com.alibaba.cloud.ai.graph.CompiledGraph} - Represents a compiled state
   * graph ready for execution.</li>
   * <li>{@link com.alibaba.cloud.ai.graph.internal.node.Node} - Represents a node in the
   * graph with a unique identifier and an associated action.</li>
   * <li>{@link com.alibaba.cloud.ai.graph.internal.edge.Edge} - Represents an edge in the
   * graph with a source ID and a target value.</li>
