Make app fully portable, remove installers

- Remove MSI and NSIS installer targets, only produce vesper.exe
- Remove tauri-plugin-window-state, replace with manual window state
  save/restore to data/window-state.json next to the exe
- Redirect WebView2 user data (including localStorage) to data/
  folder next to the exe via WEBVIEW2_USER_DATA_DIR
- Nothing written to AppData, registry, or any system location
- Update README with portable usage info

+## Portable
+
+Vesper is fully portable. It stores all data in a `data/` folder next to the executable:
+
+- `data/window-state.json` -- window position, size, and maximized state
+- `data/EBWebView/` -- WebView2 data including localStorage (UI zoom preference)
+
+Nothing is written to AppData, the registry, or any other system location. To move Vesper to another machine, just copy the exe (and optionally the `data/` folder to preserve settings).

 ## Design Philosophy
 
 1. **Content First** -- the reader is the primary focus; all UI chrome can be hidden
