Support for multiple Node.js versions per application (NVM or similar)

It would be extremely useful to have support for running different Node.js versions per application on the same server, either through NVM or a similar solution.

Currently, if you have two Node.js applications requiring different versions (e.g., Strapi v4 on Node 18 and Strapi v5 on Node 20), you are forced to choose a single global version that may break one of them.

This is a very common scenario for developers managing multiple projects on the same VPS. Most modern hosting platforms and tools (Railway, Render, DigitalOcean, Coolify) already support this out of the box.

Please consider adding per-application Node.js version selection in the SPanel Node.js App Manager.

Thank you.
