chess 4caa5d615d Keep Windows sandbox private desktops alive across helper exits (#44658) ...

## Why

Private desktops owned by short-lived sandbox wrappers disappear when those wrappers exit, preventing reuse across filesystem helper requests.

## What changed

- Select and cache private desktops in the calling process, keeping desktops separate for different sandbox permissions.
- Pass the desktop name through the wrapper to the restricted-token and elevated backends so helpers reuse the selected desktop.
- Separate sandbox account preparation from filesystem ACL refresh so desktop selection does not perform the wrapper's refresh.
- Propagate desktop preparation errors and require a desktop name when the wrapper's private desktop flag is set.

## Testing

Add a Windows filesystem regression test covering desktop survival and reuse across reads, writes, metadata queries, and streaming reads, plus separate read-only permissions and rejected writes. Extend wrapper argument tests to cover named desktops and rejection of a missing desktop name.
