refactor(cross_context): 重构S4U上下文检索逻辑并更新配置

Browse Source 
将S4U（Search for User）上下文检索模式从依赖于共享组（ContextGroup）的配置中解耦，改为使用独立的全局配置。这使得S4U模式的管理更加清晰和灵活。

主要变更：
- **配置模型更新**: 在`CrossContextConfig`中移除了与S4U相关的字段（如`s4u_ignore_whitelist`），并添加了新的S4U专用配置项，包括`s4u_mode`, `s4u_limit`, `s4u_stream_limit`, `s4u_whitelist_chats`, 和 `s4u_blacklist_chats`。
- **S4U逻辑重构**: `build_cross_context_s4u`函数不再接收`context_group`参数，而是直接读取全局的S4U配置来检索用户在白名单或黑名单聊天中的消息。
- **简化调用**: `Prompt.get_cross_context_prompt`中的调用逻辑被简化，以适应新的函数签名。
- **文档与模板更新**: 更新了`bot_config_template.toml`配置文件模板，以反映新的S4U配置结构，并提供了更清晰的注释说明。

此次重构将Normal模式（群组共享）和S4U模式（用户中心）的配置和实现完全分离，提高了代码的可维护性和配置的直观性。
