CI build failure: npm blocked by network isolation rules in command metadata refresh pipeline

[gavinbarron]

Description

The command metadata refresh pipeline is failing because network isolation rules are blocking npm access to the public registry (registry.npmjs.org). This prevents installation of autorest, autorest core, rush, and rush dependencies.

Root Cause

The pipeline installs npm packages (autorest, rush) directly from the public npm registry. Network isolation rules in the build environment block outbound access to registry.npmjs.org.

Proposed Fix

• Create a PowerShell script (\ ools/Configure-PrivateNpmFeed.ps1\) that configures \.npmrc\ files to use the private Azure Artifacts npm feed (\PowerShell_V2_Build\)
• Update \install-tools.yml\ to run the script and authenticate via \
  pmAuthenticate@0\ before installing autorest and rush
• Overwrite the Rush \.npmrc\ at build time so external contributors can still clone and install from the public feed
