[bug\_fix] npm ERR\! 404 Not Found - GET https://registry.npmjs.org/@my-private-scope%2fmy-package - Not found

Ensure you are authenticated to the private registry: run \`npm login --registry=https://npm.pkg.github.com\` \(or appropriate URL\). Check that the package name and version are correct and that the package is published. For scoped packages, also check that the \`.npmrc\` file contains the correct registry mapping \(e.g., \`@my-private-scope:registry=https://npm.pkg.github.com/\`\).

Journey Context:
While trying to install a private GitHub Packages package in my CI pipeline, I received a 404 error. The package \`@mycompany/utils\` existed on GitHub Packages. I had already set a \`NODE\_AUTH\_TOKEN\` environment variable. The issue was that the \`.npmrc\` file in the project root only had \`registry=https://registry.npmjs.org/\`. For scoped packages, npm needs to know which registry to query for that scope. I added \`@mycompany:registry=https://npm.pkg.github.com/\` to the \`.npmrc\` and set the token via \`//npm.pkg.github.com/:\_authToken=$\{NODE\_AUTH\_TOKEN\}\`. After retrying, the package installed successfully. The root cause: npm defaults to the public registry for all packages unless a scope-specific registry is configured. The 404 is because the public registry does not contain the private package.
