tools.func: pin npm to 11.11.0 to work around Node.js 22.22.2 regression

[MickLesk]

✍️ Description

Node.js 22.22.2 ships with a broken npm self-upgrade path where 'npm install -g npm@latest' fails with MODULE_NOT_FOUND for promise-retry. Pin to npm@11.11.0 as a known-good version until the upstream issue is resolved. Ref: nodejs/node#62425, npm/cli#9151
