fix(modal): prevent duplicate ModalManager declaration

window.ModalManager was set unconditionally, causing "Identifier
'ModalManager' has already been declared" when script tag in HTML
also loaded ModalManager before renderer.js required it.

Now checks !window.ModalManager before setting.

-# Building MarkdownConverter with Tauri 2.x
-
-## Prerequisites
-
-1. **Node.js 18+** and npm
-2. **Rust 1.75+** — install via [rustup](https://rustup.rs/)
-
-```bash
-# Install Rust
-winget install Rust.Rustup  # Windows
-# OR
-curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh  # macOS/Linux
-
-# Set stable as default
-rustup default stable
-
-# Install Tauri CLI (alternative to npm package)
-cargo install tauri-cli --locked
-```
-
-## Development
-
-```bash
-# Install dependencies
-npm install
-
-# Run frontend dev server
-npm run dev
-
-# In another terminal, run Tauri dev
-npm run tauri:dev
-
-# Or use Tauri CLI directly (if installed globally via cargo)
-cargo tauri dev
-```
-
-## Production Build
-
-```bash
-# Build the frontend first
-npm run build:frontend
-
-# Then build Tauri app
-npm run tauri:build
-
-# Output:
-#   Windows: src-tauri/target/release/markdown-converter.exe
-#   Installer: dist/MarkdownConverter-Setup-4.3.0.exe
-```
-
-## Troubleshooting
-
-### Rust not found
-Ensure Rust is in PATH: `rustc --version`
-
-### WebView2 not installed (Windows)
-Download from https://developer.microsoft.com/en-us/microsoft-edge/webview2/
-
-### pandoc not found
-Pandoc must be installed and in PATH. Download from https://pandoc.org/installing.html
-
-## File Structure
-
-```
-src-tauri/
-  src/
-    main.rs        # Binary entry point
-    lib.rs         # Tauri app setup + command registration
-    commands/      # Rust commands (file, git, pdf, export, etc.)
-    menu.rs        # Native menu
-    tray.rs        # System tray
-    pdf_ops.rs     # PDF processing
-    plugin_manager.rs
-    error.rs
-  Cargo.toml
-  tauri.conf.json
-  capabilities/default.json
-  icons/
-src/
-  renderer.js     # Main renderer (updated for Tauri invoke/listen)
-  tauri-commands.js  # Tauri command bridge
-  index.html      # Main HTML (copied to dist/index.html)
-dist/
-  index.html      # Built frontend output
-```

-## Key Differences from Electron
-
-| Aspect | Electron | Tauri |
-|--------|----------|-------|
-| IPC | ipcRenderer.invoke() | invoke() from @tauri-apps/api |
-| Events | ipcRenderer.on() | listen() from @tauri-apps/api |
-| File access | Node.js fs module | Rust std::fs or tauri-plugin-fs |
-| Native menus | Electron Menu API | tauri menu API |
-| Settings | electron-store | tauri-plugin-store |
-| Binary size | ~150MB | ~10MB |
