  Refine README opening to emphasize 'pure NumPy' and 'pedagogical tool'

  Why:

  CURRENT

  You've seen openai/gpt-2.
  You've seen karpathy/minGPT.
  You've even seen karpathy/nanoGPT!
  But have you seen picoGPT??!?
  `picoGPT` is an unnecessarily tiny and minimal implementation of GPT-2 in plain NumPy. The entire forward pass code is 40 lines of code.

  COPY-PASTE FIX

  Copy

  picoGPT is an **unnecessarily tiny and minimal implementation of GPT-2 in pure NumPy**, designed specifically as a **pedagogical tool** to understand the core mechanics of large language models. Unlike other minimal GPT implementations (like minGPT or nanoGPT which use PyTorch), picoGPT achieves its goal without relying on deep learning frameworks. The entire forward pass code is 40 lines of code.

  What are simple, minimal Python implementations of large language models for educational purposes?

  you: not recommended
  AI recommended (in order):

  1. nanoGPT (karpathy/nanoGPT)
  2. minGPT (karpathy/minGPT)
  3. Hugging Face Transformers (huggingface/transformers)
  4. PyTorch nn.Transformer (pytorch/pytorch)
  5. Karpathy's "Let's build GPT" YouTube series code
