Probe v2.3.0

Added

• Duplicate environments from the Environment Manager context menu or
  with Command+D on macOS (Ctrl+D on Windows and Linux).

Fixed

• Cancel stale folder dialogs and dismiss stale folder views after external collection
  changes; retain unsaved documentation without allowing writes to a different folder.

• Reject unsafe filenames when creating or duplicating unbundled environments,
  preventing environment names from directing writes outside the environment directory.

• Keep the sidebar folder selection from moving to a different folder when a
  collection changes on disk, so keyboard rename and delete cannot act on the wrong folder.
