[BUG] running npm create mastra@1.3.14 still tries to run mastra@latest after th npm dependencies installed step

[natilivni]

Describe the Bug

I can not run npm create mastra@latest due to enterprise npm feed policy. However, when I attempt to install an older version (eg. npm create mastra@1.3.14), the install script still attempts to install @latest.

Here is the err output:

Project creation failed: Failed to install Mastra CLI: Failed to install mastra@latest: Command failed: npm install --audit=false --fund=false --loglevel=error --progress=false --update-notifier=false -D mastra@latest
npm error code ETARGET
