Bahex f69a812055 fix(hooks): updating $env.config now correctly updates config state. (#16021)
- fixes #14946

- related #15227
- > [When I run nushell with the hook, the hook itself works as
expected, correctly detects system theme and changes
$env.config.color_config. However, it seems that the change to
$env.config.color_config is not propagated outside the
hook](https://github.com/nushell/nushell/issues/15227#issuecomment-2695287318)
- > [But it suffers from the same problem - modifications made to the
$env.config variable are not visible outside of the hook (which I'm not
sure if is correct behavior or
bug).](https://github.com/nushell/nushell/issues/15227#issuecomment-2695741542)
- > [I also managed to get it working with def --env, but there was one
more issue, I had to change $env.config.hooks.pre_prompt = [{
switch_theme }] into $env.config.hooks.pre_execution = ([ switch_theme
])](https://github.com/nushell/nushell/issues/15227#issuecomment-2704537565)
(having to use a string hook rather than a closure)

# Description

Recently realized that changes made to `$env.config` in closure hooks
don't take effect whereas string hooks don't have that problem.

After some investigation:
- Hooks' environment was not preserved prior to #5982 >
[2309601](2309601dd4/crates/nu-cli/src/repl.rs (L823-L840))
- `redirect_env` which properly updates the config state was implemented
afterwards in #6355 >
[ea8b0e8](ea8b0e8a1d/crates/nu-engine/src/eval.rs (L174-L190))

Simply using `nu_engine::eval::redirect_env` for the environment update
was enough to fix the issue.

# User-Facing Changes
Hooks can update `$env.config` and the configuration change will work as
expected.

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.
