`msvc-crt-static = false` has no effect

Hi, there's some issue with how you build the config graph.

Supplying a `dist.toml` with

```toml
[dist]
msvc-crt-static = false
```
Has no effect. No matter the value.

### Reproduce

On windows with dist 0.28.0

1. `cargo new foo`
2. Set `authors` and `repository` in `Cargo.toml`
3. `git commit -am "initial"`
4. `dist init` and click through defaults
5. `dist init build --allow-dirt --print=linkage`

You will get this output
```console

```
6. Add `msvc-crt-static = false` at the end of `dist-workspace.toml` as described in [the docs](https://opensource.axo.dev/cargo-dist/book/reference/config.html#msvc-crt-static)

You get the same output

7. Change this line to always evaluate to false https://github.com/axodotdev/cargo-dist/blob/b96f4b7d6f3e9e5c36e25b08a63306df83d8893f/cargo-dist/src/build/cargo.rs#L94
8. `dist init build --allow-dirt --print=linkage`

Output:

Start with cargo-dist/src/build/cargo.rs at line 94 and trace how the msvc-crt-static value from dist-workspace.toml enters the config graph. Reproduce the Windows build with dist init build --allow-dirt --print=linkage, then confirm that changing the setting changes the reported runtime libraries as expected.
