Live docs still show gpui-kit = "0.6" while examples use 0.7 API (open_window)

The live documentation at https://gpui-kit.com/docs/installation/ (and related Getting Started examples) still recommend:

gpui-kit = "0.6"

But the example code uses the 0.7 API, including:

open_window(WindowOptions::default(), cx, |_, cx| {
    cx.new(|_| HelloWorld)
})

This causes a compile error for anyone following the docs:

cannot find function `open_window` in this scope
not found in this scope (rustc E0425)

Changing the dependency to 0.7.0 makes the error go away.

Expected behavior

• The published docs for the latest version should show a matching version requirement, e.g. gpui-kit = "0.7" (or "0.7.0").
• Example code and the declared dependency version should stay in sync.

Actual behavior

Source status

The Markdown source on main is already correct and uses the template placeholder:

gpui-kit = "{{gpui_kit_version}}"

See: https://github.com/longbridge/gpui-kit/blob/main/website/docs/installation.md

The problem is that the published website for the default / docs is still serving a stale build (or an incorrect GPUI_KIT_VERSION / snapshot).

Steps to reproduce

1. Create a new project following https://gpui-kit.com/docs/installation/
2. Use the documented dependency gpui-kit = "0.6"
3. Paste the Getting Started example that calls open_window
4. Observe: cannot find function open_window in this scope
5. Change to gpui-kit = "0.7.0" → error disappears

Suggested fix

Rebuild / re-publish the latest documentation so that {{gpui_kit_version}} resolves to the current release (0.7.0) for the default site at gpui-kit.com.
