feature: latex/typst/image previewing through the new vim.img api in neovim 0.13

Is your feature request related to a problem? Please describe.

the math blocks preview looks ugly and doesn't support typst

Describe the solution you'd like

i already done most of the work (deepseek did all of it tbh)

Describe alternatives you've considered

i saw guys at emacs doing it, i can point you at them but it is useless since i already have a working example
