Module session 

Session 模块

提供 session 管理功能，包括：

• SessionStore trait: 可插拔的存储抽象
• SessionManager: 向后兼容的静态方法（使用全局 store）
• SQLite 默认实现

使用方式

方式 1: 使用默认 SQLite 存储（向后兼容）

use aster::session::SessionManager;
let session = SessionManager::create_session(dir, name, session_type).await?;

方式 2: 注入自定义存储（推荐）

use aster::session::{SessionStore, NoopSessionStore};
use aster::agents::Agent;

let store = Arc::new(MyCustomStore::new());
let agent = Agent::new().with_session_store(store);
