Add type save env variables using @t3-oss/env-core

[atybdot]

What you think of creating an optional add-on that will make sure that env variables are not empty or undefined on the start of app. using @t3-oss/env-core?.

Limitations

• the library @t3-oss/env-core requires global envoirment such as proccess.env or bun.env and hence it will be difficult to make it work on cloudflare workers, (for example in hono).

see the env-core docs for more info
