How would we use the global bun object, such as when use .file()

[KyleFontenot]

Bun's latest version does have file I/O, but the api uses a global Bun object which I can't seem to access from a server endpoint using the adapter. Thought maybe the adapter would have to be updated if the bun dependency is.

Thought maybe I could try import Bun from 'bun' (after installing bun) I get:

Internal server error: Failed to resolve entry for package "bun".
