create a group for dev dependencies, there is no need to install all this other stuff just for speedrun and it's exposing people to dependency chain attacks. we need to delete more dependencies. dependencies bad bad bad

delete torchao dependency, create our own exact API-matched version of Float8Linear, document it very well. for some poorly understood reason, the performance is not only ~identical but actually runs 3% faster. despite of it being significantly simpler and much less code. i don't fully understand why/how atm

alright add transformers as a dep of the repo because it should be easy to evaluate the CORE score of HF models. Not super happy about it but i tried it and the uv.lock doesn't get bloated as much as i expected

replace files-to-prompt with git ls-files for bloat metrics
...
files-to-prompt was including untracked files (knowledge/, dev scripts, etc.) which inflated the bloat metrics. now we use git ls-files to only count tracked source files, which is more accurate and removes an external dependency.

delete the inline rustbpe project. it was ugly to have a project within project and rustbpe is now nicely a separate repo on my github karpathy/rustbpe and it's on pypi etc., so we just add it as a depedency to uv. i think it is appropriate that this is a separate repo because 1) it doesn't have too many knobs, other than the ones that are exposed - the regex pattern and vocab size and 2) all of its complexity is not algorithmic (it's equivalent to minbpe), instead it is efficiency-related, so it is ok to hide relatively speaking

numpy isnt acting as a dependency for nanochat, so isnt it better to remove numpy from dependencies list

add support for CPU and for MPS. I had to change a few cosmetic things. I also discovered I think a bit of a bug, where I was casting wte to bfloat16 in the wrong place (the model init) instead of in init_weights
