Fix artifact extraction and stream SwiftPM resolve output

The SwifterPM dependency used by tuist install and tuist generate is bumped to 0.8.12. Top-level __MACOSX AppleDouble shadow bundles are stripped from extracted archives and skipped during recursion, so generating against Finder-zipped binary artifacts like Plaid’s LinkKit no longer aborts with a missing Info.plist error. Delegated swift package resolve runs now stream stdout and stderr while still capturing output for callers, so resolution shows SwiftPM progress instead of appearing stalled.
