SwifterPM update fixes __MACOSX artifacts, resolve output, and restore paths

The SwifterPM dependency has been updated to 0.8.12, fixing two issues: Finder-zipped binary artifacts (such as Plaid’s LinkKit) that carry a __MACOSX AppleDouble sidecar no longer confuse the artifact scanner with shadow xcframeworks, and swift package resolve progress output is now streamed to the user instead of appearing stalled. A subsequent 0.8.13 update also fixes restore path handling by using SwiftPM’s artifact scratch path.
