Manual checks are added to `parse_let`, `parse_mut`, and `parse_const`. `parse_var_with_opt_type` is also fixed to update `spans_idx` correctly. Fixes #12125. It's technically a fix, but I'd rather not merge this directly. I'm making this PR to bring into attention the code quality of the parser code. For example: * Inconsistent usage of `spans_idx`. What is its purpose, and which parsing functions need it? I suspect it's possible to remove the usage of `spans_idx` entirely. * Lacking documentation for top-level functions. What does `mutable` mean for `parse_var_with_opt_type()`? * Inconsistent error reporting. Usage of both `working_set.error()` and `working_set.parse_errors.push()`. Using `ParseError::Expected` for an invalid variable name when there's `ParseError::VariableNotValid` (from `parser.rs:5237`). Checking variable names manually when there's `is_variable()` (from `parser.rs:2905`). * `span()` is a terrible name for a function that flattens a bunch of spans into one (from `nu-protocal/src/span.rs:92`). The top-level comment (`Used when you have a slice of spans of at least size 1`) doesn't help either. I've only looked at a small portion of the parser code; I expect there are a lot more. These issues made it much harder to fix a simple bug like #12125. I believe we should invest some effort to cleanup the parser code, which will ease maintainance in the future. I'll willing to help if there is interest. |

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.
