Feature Request: Add progress indicators for long-running background tasks

Problem:
When running long operations like zip compression in background bash shells, there's no way to see progress. Users have to repeatedly ask "is it done yet?"

Suggested Solution:
Add progress indicators for background tasks, especially for:

• File compression (zip, tar, etc)
• Large file transfers
• Long compilations
• Any background Bash command

Benefits:

• Better user experience
• Reduces need for repeated status checks
• Users can estimate completion time

Use Case:
Compressing 18GB folder - took 15 minutes with no visibility into progress.
