docs: update README with new Rust frontend and fix TypeScript version

- Updated README.md to reflect the addition of a native Rust frontend using egui
- Added setup instructions for the new rust-frontend directory
- Modified frontend package.json to downgrade TypeScript version from 5.3.3 to 4.9.5 due to conflicts
- Updated path references in documentation from ComfyUI-Rust/ to direct paths
- Reorganized project structure documentation to distinguish between original and new frontends

+# ComfyUI Rust Frontend
+
+A native Rust frontend for ComfyUI-like AI image generation tool using egui.
+
+## Features
+
+- Node-based workflow editor
+- Real-time preview pane
+- Integration with backend API
+- ROCm support through Rust bindings
+
+## Architecture
+
+This frontend is built with:
+- `eframe` and `egui` for the UI framework
+- `reqwest` for HTTP communication with the backend  
+- `serde` for JSON serialization/deserialization
+
+## Project Structure
+
+```
+src/
+├── main.rs          # Main application entry point
+├── node_editor.rs   # Node-based workflow editor implementation
+├── node_panel.rs    # Panel for selecting and managing nodes
+├── preview_pane.rs  # Preview pane for image results
+└── api_client.rs    # Backend API communication layer
+```
+
+## Running the Application
+
+1. Make sure you have Rust installed (`rustup` or `curl https://sh.rustup.org/rustup.sh -sSf | sh`)
+2. Start the backend server:
+   ```bash
+   cd ../backend && cargo run
+   ```
+3. In another terminal, run the frontend:
+   ```bash
+   cd rust-frontend && cargo run
+   ```
+
+## Building
+
+To build for release:
+```bash
+cd rust-frontend && cargo build --release
+```
+
+The executable will be located at `target/release/comfyui-rust-frontend`.
+
+## Integration with Backend
+
+This frontend communicates with the backend through HTTP API endpoints. The API client handles:
+
+- Fetching available node types from `/nodes`
+- Executing workflows via POST to `/execute` 
+- Getting execution results and preview images
+
+The backend must be running on `http://localhost:8080` by default, but this can be configured in `src/main.rs`.
