• Added Node.js 26.5.0 (linux-amd64)
• Fixed npm install failing on npm 12, which removed the --unsafe-perm flag the buildpack was passing. (#1704)
• Relocated the npm binary installation (npm@<version> bootstrap) into lib/package_managers/npm.sh as part of the error-handling migration. This is a behavior-neutral move; the build errors and their messages are unchanged. (#1701)
• Improved the Node.js version-resolution build errors, and added error handling for previously-unclassified resolver failures. (#1698)
