重构图像生成和搜索工具；更新主代理来处理输入图像

- 更新了“generate_image.py”以接受输入图像以增强图像生成。
- 修改了`pexels_search.py​​`和`unsplash_search.py​​`以将日志记录和上传路径从“explorer”更改为“explore”。
- 调整了“print_graph”和“sketch_graph”以提取最新的用户输入并处理输入图像以生成打印和草图图像。
- 重构“generate_print_tool”和“generate_sketch_tool”以接受输入图像。
- 更新了“main_agent.py”以包含状态中的输入图像并调整了图形构建过程。
- 增强了“service.py”来管理输入图像并改进了流媒体期间的事件处理。
- 更新了新软件包和版本的“pyproject.toml”和“uv.lock”中的依赖项。
