Support for opening .lnk files on Windows

Feature Request: Support for opening .lnk files on Windows

Problem

Currently, Spacedrive on Windows does not handle .lnk shortcut files correctly. Opening a .lnk file might not open the actual target, and Spacedrive doesn't show compatible applications for the shortcut's target.

Proposed Solution

Implement .lnk resolution in the Windows file opening backend. When a .lnk file is encountered:

1. Resolve it to its actual target path using IShellLink.
2. Open the target path instead of the shortcut file.
3. For getting compatible apps, use the target's extension instead of .lnk.

Implementation Details

Use windows-rs with IShellLinkW and IPersistFile to resolve the shortcut. This requires the Win32_Storage_FileSystem feature in the windows crate.
