The download_found option downloads already-cracked hashes (with cleartext
passwords). These cannot be used for cracking, so the 'Switch to this hashfile
for cracking?' prompt is inappropriate and confusing.
The switch prompt is kept for download_left since those are uncracked hashes
that can be cracked.
- Remove the switch-to-cracking prompt from download_found flow
- Add clarifying message that found hashes are already cracked
- Align with intended behavior: download_left prompts to switch, download_found just downloads
