Reworking some of the sprawling code we use to generate the `help cmd` or `cmd --help` output. This touches mainly the rendering and not the gathering of the necessary data (see open bugs under [label:help-system](https://github.com/nushell/nushell/issues?q=sort%3Aupdated-desc+is%3Aopen+label%3Ahelp-system)) Fixes #9076 Fixes the syntax shape output on flags to be consistent. ## Example ```nushell def test [ positional: int, documented: float, # this has documentation default = 50, optional?, --a = "bla", --bla (-b) = "bla", # named with default ] {} ``` ### before  ### after 
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.
