  Reposition README H1 and opening paragraph to highlight core differentiator

  Why:

  CURRENT

  # SageAttention
  This repository provides the official implementation of SageAttention, SageAttention2, and SageAttention2++, which achieve surprising speedup on most GPUs without lossing accuracy across all models in a plug-and-play way.

  # SageAttention: Quantized Attention for 2-5x Speedup over FlashAttention
  This repository provides the official implementation of SageAttention, SageAttention2, and SageAttention2++. It introduces novel quantized attention mechanisms that achieve a 2-5x speedup compared to FlashAttention, without losing end-to-end metrics across language, image, and video models, in a plug-and-play way.

  Add a dedicated 'Comparison' section to the README

  Why:

  COPY-PASTE FIX

  Copy

  Add a new section, perhaps after 'Current Features', titled '## Comparison with FlashAttention and other Baselines' or similar, detailing the speedup and accuracy benefits.
