Why

• Existing NVM installations without a default leave Node unusable, and failed npm inventory must not be treated as a safe migration.

How

• Keep a verified default unchanged; install LTS when NVM has no default and its installed versions can be inspected.
• Parse only the Default line, avoiding confusion with a previous version.
• Stop migration when npm is missing, returns an error, or reports a package without a version.

Tests

• powershell.exe -NoProfile -File tests/windows-node-tests.ps1 and PowerShell 7: passed with isolated fake NVM and npm commands.
• git diff --check main..HEAD: passed.
• Real migration of the earlier implementation was tested in Windows Sandbox; these additional failure cases have not been exercised in a fresh VM.

Related to #2. Further VM scenarios and end-to-end PATH checks remain open.
