Ballast 0.3.1

• iCloud Drive: large files in a Desktop or Documents folder synced with iCloud are marked in iCloud, and removing them needs I understand, because it removes them from every device.
• Python: removing a Python version names the pipx apps and Poetry, Pipenv or Hatch environments built on it.
• RVM: Uninstall RVM completely names the Rubies you use by default or projects pin.
• Apps: background helpers an app left in ~/Library/LaunchAgents are stopped before they go to the Trash.
• pnpm: the pnpm store now shows only what pnpm store prune frees, the packages no project links to, instead of the whole store.
• Project leftovers: build folders under 1 MB are no longer listed.
• Login items: two leftover login items with the same name no longer clash.
• make notarize signs and notarises a release, for when there's a Developer ID to sign with.
• New screenshots, including Safe to reclaim.
