Cortex Software / Mod installation manager
Tailmark
Tailmark treats installing a mod as an operation that should be inspected, reversible, and recorded. Archives are opened and classified before anything is written, conflicts and duplicates are flagged, replaced content is backed up, and a failed operation rolls back instead of leaving a half-installed mess.
