Subject: [PATCH] fix: create parent dirs for downloads with subdirectory paths

Some archive.org file names include directory prefixes
(e.g. "ZERO-G - Deepest India/vocal.iso"). MkdirAll only
created the output root, not intermediate directories.
Added filepath.Dir(MkdirAll) in both downloadFile (CLI)
and handleAPIDownload (web).
