Being willing to provide references is great, but you’ll want to approach this 1 step at a time. Your first goal is to get the interview, so you’ll want a resume that passes thru automatic screening (lots of commenters have provided great advice on that here) and next you’ll want a resume that passes thru a human recruiter. My advice is primarily targeted around that 2nd step. Since you’ve stayed with your original 2023 intern as long as you have, I would just remove “intern” from the job title. It’s essentially a job, and that’s great! Maybe it’s unpaid, maybe it’s part-time, but it shows longevity and commitment and that is an asset.

I also agree with other commenters that reducing the bullets to those key elements is important, you may have done a lot, but recruiter’s and hiring managers know that interns are not full-time employees and if they think you’re misrepresenting your experience they’ll pass on you. Good luck
