Investigate: should @yas/env update NODE_ENV?

[kasper573]

Since @yas/env resolves node env like this:

node_env = env.NODE_ENV || env.VERCEL_ENV || "development"

would it not be reasonable to launch the command with that value set to NODE_ENV. this would ensure that mode becomes preview in the following example:

../.. postinstall: @yas/trpc-server:build: 🚀 Loading env flow for preview
../.. postinstall: @yas/trpc-server:build: [[email protected]]: ".env*" files loading failed: no ".env*" files matching pattern ".env[.preview][.local]" in "/vercel/path0/apps/trpc-server" dir undefined
../.. postinstall: @yas/trpc-server:build: ✅  Validated env using: /vercel/path0/apps/trpc-server/src/env.ts
../.. postinstall: @yas/trpc-server:build: {
../.. postinstall: @yas/trpc-server:build:   "env": {
../.. postinstall: @yas/trpc-server:build:     "mode": "development",
