bugfixes and writing docs

---

i spent a good 4 hours just going through some code, finding anything that might be wrong and fixing them. surprisingly, i didnt find that much, which means that i’m better at coding than i thought
 

i found a few places where i just forgot to add something to a cleanup function, which could have led to a small memory leak over time, but nothing major

 
some bugs i fixed:

• the background of any dropdown menu was rendering behind the viewport
• selecting stuff in the hierarchy wouldnt sync with the inspector properly
• i forgot to add screenPointToRay to my cleanup function
• some other things that i forgot
   

i also added a few std::couts in some spots that needed them

---

i also decided to start writing some docs because my brain was fried
 

i basically just dug through my ~3000 lines of vulkan init and rendering code, and took notes throughout and tried explaining my confusing mental processes in a .md file
 

this kinda made me realize that i do not have enough annotation in my code but thats a problem for future me :)
