This PR just tidies up some tests by removing unused code: 1. If the filesystem is not touched, don't use the filesystem playground/sandbox 2. If the filesystem is not touched, don't specify the `cwd` 3. If the command is short, don't bother wrapping it in `pipeline()` 4. If the command doesn't have quotes, don't bother with a `r#"..."#` raw string Part of #8670.
Nushell core libraries and plugins
These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.
Foundational libraries are split into two kinds of crates:
- Core crates - those crates that work together to build the Nushell language engine
- Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.
Plugins are likewise also split into two types:
- Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
- Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
