Subject: [PATCH] feat(website): Restructure TOC with pedagogically-sound
 three-tier learning pathway
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reorganized Jupyter Book navigation from scattered sections to coherent ML systems progression:

🏗️ Foundation Tier (01-07): Core systems building blocks
- Tensor, Activations, Layers, Losses, Autograd, Optimizers, Training
- Universal ML computational primitives everyone needs

🧠 Intelligence Tier (08-13): Modern AI algorithms implementation
- DataLoader, Spatial, Tokenization, Embeddings, Attention, Transformers
- Core algorithms that define modern ML systems (not "applications")

⚡ Optimization Tier (14-19): Production systems engineering
- KV-Caching, Profiling, Acceleration, Quantization, Compression, Benchmarking
- Making intelligent algorithms fast, efficient, and scalable

🏅 Capstone Project (20): AI Olympics integration

This mirrors real ML systems engineering roles and builds proper conceptual
understanding for production ML systems work. Students need to understand
the intelligence algorithms before they can optimize them effectively.
