Add test support crate for plugin developers (#12259) # Description Adds a `nu-plugin-test-support` crate with an interface that supports testing plugins. Unlike in reality, these plugins run in the same process on separate threads. This will allow testing aspects of the plugin internal state and handling serialized plugin custom values easily. We still serialize their custom values and all of the engine to plugin logic is still in play, so from a logical perspective this should still expose any bugs that would have been caused by that. The only difference is that it doesn't run in a different process, and doesn't try to serialize everything to the final wire format for stdin/stdout. TODO still: - [x] Clean up warnings about private types exposed in trait definition - [x] Automatically deserialize plugin custom values in the result so they can be inspected - [x] Automatic plugin examples test function - [x] Write a bit more documentation - [x] More tests - [x] Add MIT License file to new crate # User-Facing Changes Plugin developers get a nice way to test their plugins. # Tests + Formatting Run the tests with `cargo test -p nu-plugin-test-support -- --show-output` to see some examples of what the failing test output for examples can look like. I used the `difference` crate (MIT licensed) to make it look nice. - :green_circle: `toolkit fmt` - :green_circle: `toolkit clippy` - :green_circle: `toolkit test` - :green_circle: `toolkit test stdlib` # After Submitting - [ ] Add a section to the book about testing - [ ] Test some of the example plugins this way - [ ] Add example tests to nu_plugin_template so plugin developers have something to start with

Split the plugin crate (#12563) # Description This breaks `nu-plugin` up into four crates: - `nu-plugin-protocol`: just the type definitions for the protocol, no I/O. If someone wanted to wire up something more bare metal, maybe for async I/O, they could use this. - `nu-plugin-core`: the shared stuff between engine/plugin. Less stable interface. - `nu-plugin-engine`: everything required for the engine to talk to plugins. Less stable interface. - `nu-plugin`: everything required for the plugin to talk to the engine, what plugin developers use. Should be the most stable interface. No changes are made to the interface exposed by `nu-plugin` - it should all still be there. Re-exports from `nu-plugin-protocol` or `nu-plugin-core` are used as required. Plugins shouldn't ever have to use those crates directly. This should be somewhat faster to compile as `nu-plugin-engine` and `nu-plugin` can compile in parallel, and the engine doesn't need `nu-plugin` and plugins don't need `nu-plugin-engine` (except for test support), so that should reduce what needs to be compiled too. The only significant change here other than splitting stuff up was to break the `source` out of `PluginCustomValue` and create a new `PluginCustomValueWithSource` type that contains that instead. One bonus of that is we get rid of the option and it's now more type-safe, but it also means that the logic for that stuff (actually running the plugin for custom value ops) can live entirely within the `nu-plugin-engine` crate. # User-Facing Changes - New crates. - Added `local-socket` feature for `nu` to try to make it possible to compile without that support if needed. # Tests + Formatting - :green_circle: `toolkit fmt` - :green_circle: `toolkit clippy` - :green_circle: `toolkit test` - :green_circle: `toolkit test stdlib`
