Description
Describe the feature
I am currently deploying a new TanStack Start app with node server in containers.
We like to use custom basepaths for production and staging systems and I'm used to setting a new basepath at runtime from other projects, but nitro sets the basepath in the index.mjs file at build time.
It would be great if even after build the basepath can be modified via an env var.

Research direction
Start by tracing how Nitro writes the basepath into the generated index.mjs during the build. Then inspect the existing environment-variable handling for the Node server and determine where a runtime override can be applied after build. Done means a deployed container can select its basepath through an environment variable, with coverage for the runtime behavior.
