Config file loading rules

1. default_config.nu and default_env.nu refer to the files that are compiled inside of the nushell executable and are also located in our repo.
2. personal env.nu/config.nu/login.nu refer to the files that are in the $nu.default-config-dir that you have personally edited.
3. specified config.nu/env.nu refer to files that are specified on the command line with the --config and --env-config command line parameters.

nu

• ✅ Always reads the nushell standard library
• ✅ Always reads personal plugin.msgpackz file if it exists
