Description
### Describe the bug, including details regarding any error messages, version, and platform.
See https://github.com/r-universe/cran/actions/runs/29991693952/job/89157083157
The problem is that it is using static libs for win x64:
```
** using staged installation
*** pkg-config found.
trying URL 'https://github.com/apache/arrow/releases/download/apache-arrow-25.0.0/r-libarrow-windows-x86_64-25.0.0.zip'
```
Sadly `Sys.setenv("LIBARROW_BINARY" = FALSE)` does not seem to work on Windows either.
### Component(s)

Research direction
Start with the linked GitHub Actions job and inspect the R binding build configuration and the handling of LIBARROW_BINARY on Windows. Confirm why the WinARM build selects the win x64 static archive, then verify that the R bindings build successfully on WinARM without that incorrect artifact.
