This pr fix clippy warnings in latest clippy version(1.72.0): Unfortunally it's not easy to handle for [try fold](https://rust-lang.github.io/rust-clippy/master/index.html#/manual_try_fold) warning in `start command` Refer to known issue: > This lint doesn’t take into account whether a function does something on the failure case, i.e., whether short-circuiting will affect behavior. Refactoring to try_fold is not desirable in those cases. That's the case for our code, which does something on the failure case. So this pr is making a little refactor on `try_commands`.
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.
