feat(plugin): 引入Prompt组件系统以实现动态Prompt注入

引入了一个新的插件组件类型 `BasePrompt`，允许插件动态地向核心Prompt模板中注入额外的上下文信息。该系统旨在提高Prompt的可扩展性和可定制性，使得开发者可以在不修改核心代码的情况下，通过插件来丰富和调整模型的行为。

主要变更包括：
- **`BasePrompt` 基类**: 定义了Prompt组件的标准接口，包括 `execute` 方法用于生成注入内容，以及 `injection_point` 属性用于指定目标Prompt。
- **`PromptComponentManager`**: 一个新的管理器，负责注册、分类和执行所有 `BasePrompt` 组件。它会在构建核心Prompt时，自动查找并执行相关组件，将其输出拼接到主Prompt内容之前。
- **核心Prompt逻辑更新**: `src.chat.utils.prompt.Prompt` 类现在会调用 `PromptComponentManager` 来获取并注入组件内容。
- **插件系统集成**: `ComponentRegistry` 和 `PluginManager` 已更新，以支持 `BasePrompt` 组件的注册、管理和统计。
- **示例插件更新**: `hello_world_plugin` 中增加了一个 `WeatherPrompt` 示例，演示了如何创建和注册一个新的Prompt组件。
- **代码重构**: 将 `PromptParameters` 类从 `prompt.py` 移动到独立的 `prompt_params.py` 文件中，以改善模块化和解决循环依赖问题。
