feat: implement task management store with IPC integration

- Added a new task store in `src-react/stores/task.ts` to manage tasks and their statuses.
- Implemented functions for creating, executing, and retrying tasks, along with handling task progress and completion.
- Introduced persistence for tasks using IPC.
- Created utility functions for normalizing room types and building subtasks.
- Added a new CSS file for global styles in `src-react/styles.css`.
- Created runtime types in `src-react/types/runtime.ts` and exported them.
- Updated the main entry points for Vue and React applications to support dynamic framework loading.
- Refactored chat model interfaces and utility functions into `src/shared/chat-model.ts`.
- Updated TypeScript configuration to include paths for React components and types.
- Enhanced Vite configuration to support both Vue and React frameworks.
