The repository includes a VS Code Webview extension that reuses the frontend in
www/. To test it locally:
npm install
npm run package
Then open the generated .vsix file in VS Code with Extensions: Install from
VSIX.... After installation, run Postdim: Open API Client from the
Command Palette.
The extension scaffold and packaging metadata are in the repository root. The
publisher value in package.json must match a publisher created at
marketplace.visualstudio.com/manage before publishing.
