The internal default environment variables (other than $env.config) that will be set during Nushell startup.
Is loaded before the user's env.nu.
Will be loaded during any startup where the user's env.nu is also loaded. For example:
- During normal startup with nu
- During a startup where the user specifies an alternative env.nu via nu --env-config <path>
- During a nu -c <commandstring> or nu <script> startup so that ENV_CONVERSIONS is properly handled for Windows.
Is not loaded when running with an explicit no --no-config-file (-n).
Is not commented - Comments are in doc_env.nu.
Should be optimized for fastest load times.
Can be introspected via config env --default | nu-highlight

`default_config.nu`:

Counterpart to default_env.nu.

Contains any $env.config values that are not set via Rust defaults.
Is loaded after the user's env.nu.
Is loaded before the user's config.nu.
Will be loaded during any startup where the user's config.nu is also loaded. For example:
- During normal startup with nu
- During a startup where the user specifies an alternative config.nu via nu --config <path>
Likewise, is never loaded during a startup where the user's config.nu would not be loaded. For example:
- nu -n/--no-config
- nu -c "ls"
- nu <script.nu>
Is not commented - Comments are in doc_config.nu.
Should be optimized for fastest load times. Whenever possible, values should be set via nu-protocol::config
- Exception: color_config values are currently set in this file so that user's can introspect the values
- TODO: Implement defaults for color_config in nu-protocol::config and remove from default_config.nu
Can be introspected via config nu --default | nu-highlight
An ideal default_config.nu (when all values are set via nu-protocol::config) will simply be:
```
$env.config = {}
```

`doc_env.nu`

A commented file documenting the most common environment variables that a user might configure in env.nu
For convenient in-shell access - Can be pretty-printed via config env --doc | nu-highlight
Since this file is for documentation only, include actual Nushell code without comments so that it can be pretty-printed
No optimization necessary - Not intended for use other than documentation.
Consider replacing config env --doc with help env.nu at some point.
Uses a mix of default values (explained) as well as other examples that users might want in their own env.nu

This file is used one-time (typically) at first startup
If the $nu.default-config-path directory does not exist, the directory is created and then both scaffold_env.nu and scaffold_config.nu are written to it
Contains only commented lines explaining the purpose of the file to the user, along with information on the config env command.
