feat: bundle WebView2 offline installer for Windows NSIS setup

- Add windows.webviewInstallMode offlineInstaller to tauri.conf.json
  so the NSIS installer embeds the full WebView2 runtime (~127MB),
  removing the need for internet or pre-installed Edge on target machines
- Add windows.nsis config with installMode both (per-user & per-machine)
- Update CI to build NSIS installer (--bundles nsis) on Windows
- Release now ships both portable exe and NSIS setup installer
- Bump version to 0.5.3
