[2026-04-25] lint | Cross-links update

  • Action: Added cross-links to all 21 wiki pages
  • Each page now links to 3-5 related pages
  • Connected: diffusion-model ↔ flow-matching ↔ vae ↔ kl-divergence
  • Connected: transformer ↔ flash-attention ↔ infini-attention ↔ deepseek ↔ qwen-series
  • Connected: llm-rl-algorithms ↔ sft-vs-rlhf ↔ grpo-global ↔ deepseek
  • Connected: deepspeed ↔ quantization ↔ pagedattention ↔ flash-attention

  • Added external-blogs references to relevant pages
