Empty directory cleanup

Usage

# Preview cleanup (dry-run)
python manage.py cleanup_old_data --days=30 --dry-run --cleanup-files

# Clean AI responses older than 60 days
python manage.py cleanup_old_data --days=60

# Full cleanup with file removal
python manage.py cleanup_old_data --cleanup-files --force

# Automated cleanup (for cron)
python manage.py cleanup_old_data --days=90 --cleanup-files --force 

Command Options

AI?

@skalwaghe-56 Nahh, I just generated the comments to enhance readability and the create_test_data.py script to test its functionality.

I would strictly recommend not using AI. AI should not be used for contributions and it is should be avoided at any costs. I request you to please not use AI in the future too. Thanks! (Open source contribution is not for AI generated code)
As per me, you should do this yourself and enjoy the process and not for some swags in the HacktoberFest.

@skalwaghe-56 Bro, chill. I've been coding for several years, and I use it as a companion to make my code more readable by documenting and commenting on it. This helps reviewers and others make proper corrections.

[skalwaghe-56]

Haha, alright, Mr. “Several Years of Coding” 😎. Just don’t let your AI buddy start writing your pull requests. You shouldn't use AI at all in open-source contribution for actual world code as per me. That would ruin all the fun of open-source!

@skalwaghe-56 Relax, the AI is the GPS, not the driver. It's here to help with the comments and docs, but I'm still the one building the engine. It's a companion, not a replacement. Meanwhile, I think the good-first-issue label is calling your name.

Nicee! Use AI here as well. Understood who is what? very clearly.

I don't like the use of all these emojies (from AI) in the command, can you clear that up please

[Pallavrai]

yeah sure
