vercel dev does not load `.env.local` or process env

[GeeWee]

I would expect the rust runtime to act approximately like NextJS and load .env and .env.local when running the dev command.

However it only seems to pick environment variables from .env and not .env.local. It seems like this logic is located here in the vercel CLI and hard-coded. I assume this means the runtime is responsible for handling of any other .env files?

If that's the case, is there any chance we can export env variables defined in the process for use in the rust serverless functions, or manually pick up and export .env.local or similar?
