Put `bunfig.toml` in global directory

[brettwillis]

Currently the auth tokens etc are written to a bunfig.toml file in the working directory. If the project is a monorepo and we run a bun install in a subdirectory, this config is not picked up.

If we can place the config in $HOME/.bunfig.toml then it would be picked up regardless of where we run bun install.

However I tried manually moving mv bunfig.toml $HOME/.bunfig.toml but bun still does not pick up the config. Could it be that bun does not expand the $BUN_AUTH_TOKEN env variable placeholder when it is in the global/home directory?

I have run into a similar issue. I need to checkout multiple repos side by side and run bun install in both and some of the install happens from a private internal github repo.

I end up with this issue, due to the fact I have to copy the bunfig.toml to multiple locations or else I end up with 401's when I run bun install.
