Fix capture logic for inner closures (#9754)
# Description

This fixes the variable capture logic for closures in two cases:

* Closures inside of closures did not properly register the closures (or
lack thereof) in the outer closure
* Closures which called their inner closures before definition did not
properly calculate the closures of the outer closure

Example of the first case:
```
do { let b = 3; def c [] { $b }; c }
```

Example of the second case (notice `c` is called before it is defined):
```
do { let b = 3; c; def c [] { $b }; c }
```

# User-Facing Changes
This should strictly allow closures to work more correctly.

# 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 -A
clippy::needless_collect -A clippy::result_large_err` to check that
you're using the standard code style
- `cargo test --workspace` to check that all tests pass
- `cargo run -- -c "use std testing; testing run-tests --path
crates/nu-std"` 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.

Nushell REPL

This directory contains the main Nushell REPL (read eval print loop) as part of the CLI portion of Nushell, which creates the nu binary itself.

Current versions of the nu binary will use the Nu argument parsing logic to parse the commandline arguments passed to nu, leaving the logic here to be a thin layer around what the core libraries.
