Sounds like a tall order. Heck, just an app that could accurately let you search screenshots would be killer. I use X-Mind 8 for a lot of this, but it’s seriously dated and slow. It’s primarily mind mapping software, but it lets you include hyperlinks and notes on objects.
I’d be happy with a fresher, more up to date version of that.
As for screenshots, I know it’s not a full-screenshot search, but there’s a neat macos app called TRex that will do image to text to clipboard conversion. It’s handy if you’re on a Mac without Monterey (which has this feature built in).
Good luck - I hope this post produces the unicorn you seek or results somewhat close.
