These are great questions. Another one since we are talking about editing the programming “code” of the human body is: what if we got it wrong? What sorts of “bugs” might occur in execution or through unforeseen interactions?
...no? This is not gene therapy. The effects of receiving a mRNA vaccine will, apart from training the immune system (which was the whole point), be next to nothing.
Your body is continually being bombarded with random foreign DNA and RNA. That's just how life on Earth works. Yes, introducing a big pile of it at once is not normal... but it's a difference of degree, not something completely new.
If anything, problems are more likely to derive from the lipid bubbles used (at least by Moderna) to package and transport the mRNA.
Noob here, could you expand on that?

edit: Here is more specific information on lipid nanoparticles in RNA vaccines, which explains that RNA vaccines that involve lipid nanoparticles tend to cause a local inflammatory effect, i.e. shoulder soreness.

It is absolutely not anything like merging a patch into the master branch.
