Major architectural shift from Next.js to a lightweight Vite + React SPA model ("Puppet Architecture") to better support real-time workflow visualization and strict type safety.
Key Changes:
1. **Architecture & Build**:
- Initialized Vite + React + TypeScript project.
- Configured Tailwind CSS v4 and Shadcn UI.
- Archived legacy Next.js frontend to 'frontend/archive/v2_nextjs'.
2. **Core Features**:
- **Dashboard**: Implemented startup page with Symbol, Market, and Template selection.
- **Report Page**:
- **Workflow Visualization**: Integrated ReactFlow to show dynamic DAG of analysis tasks.
- **Real-time Status**: Implemented Mock SSE logic to simulate task progress, logs, and status changes.
- **Multi-Tab Interface**: Dynamic tabs for 'Overview', 'Fundamental Data', and analysis modules.
- **Streaming Markdown**: Enabled typewriter-style streaming rendering for analysis reports using 'react-markdown'.
- **Config Page**: Implemented settings for AI Providers, Data Sources, and Templates using TanStack Query.
3. **Documentation**:
- Created v2.0 User Guide ('docs/1_requirements/20251122_[Active]_user-guide_v2.md').
- Implemented 'DocsPage' in frontend to render the user guide directly within the app.
4. **Backend Alignment**:
- Created 'docs/frontend/backend_todos.md' outlining necessary backend adaptations (OpenAPI, Progress tracking).
This commit establishes the full frontend 'shell' ready for backend integration.
