fix: install script mount point parsing for volume names with spaces (#34)

The hdiutil attach output parsing used awk '{print $NF}' which only
captures the last space-separated field. Volume names like
"VibeGrid 0.1.0-arm64" broke the mount path extraction. Switch to
sed + grep to capture the full /Volumes/... path.
