Subject: [PATCH] update virtual terminal processing (#13710)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

# Description

With Windows Terminal Canary 1.23.240826001-llm, this enables nushell to
query the terminal and receive a response.


![image](https://github.com/user-attachments/assets/c4c43328-c431-47e4-b377-8b3a2bc12b74)

The red component here is
```nushell
❯ ("0c0c" | into int -r 16) / 256 | math round | fmt | get lowerhex
0xc
```

This example queries the background and the response is a r/g/b color.
The response really should be
```
␛]11;1;rgb:0c0c/0c0c/0c0c
```
I'm not sure why nushell's input is eating the first part.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->

# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use toolkit.nu; toolkit test stdlib"` to run the
tests for the standard library

> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr
> ```
-->

# After Submitting
<!-- If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
