Congrats, we all had AI free apps 2 years ago, and for the 50 years before that... Keep calm and carry on, what worked then, still works now.

Or, freak out - you just might consider having an agent like Opus 5.5 review your code and write you a report of its findings... if you don't, others will - that's the new landscape. If you do get "findings" in the report, I'd be curious to hear if any of them were both valid and concerning. I'm sure you won't care about a lot of what it finds, but you might just be surprised by some things it does find.
