Interactive mode to preview and confirm deletions

Could you please provide more details on what you mean by "preview deletions"? Should the script prompt for confirmation before deleting each cache file, or do we need user confirmation before proceeding with each step (e.g., brew, Docker, Safari, etc.)?

I think the ideal behaviour would be:

• When run without flags, show what would be deleted and ask for a confirmation with y/n for each group of deletions.
• Add a flag -y/--yes to bypass the confirmations and directly delete files for scripting.

What I mean by showing what would be deleted, I think it should be something like:

cleanmac.sh would delete files older than X days:
1GiB of System caches in `~/Library/Caches`. Proceed? Y/n
2GiB of Safari caches. Proceed? Y/n
...

If too complex/slow to calculate size for each, this part could be omitted, but I think this user experience would be ideal for first-time users.

I've also included #8 in this as well.

What do you think?
