  Reposition README H1 and opening paragraph to emphasize server framework and real-time

  Why:

  CURRENT

  # sherpa
  
  `sherpa` is an open-source speech-text-text inference framework using PyTorch, focusing **exclusively** on end-to-end (E2E) models, namely transducer- and CTC-based models. It provides both C++ and Python APIs.

  # sherpa: High-Performance Real-Time Speech-to-Text Server Framework
  
  `sherpa` is an open-source, high-performance speech-to-text **server framework** for **real-time** transcription, built with PyTorch. It focuses **exclusively** on end-to-end (E2E) models (transducer- and CTC-based) and provides both C++ and Python APIs for deployment.

  Add a new section, for example, after the initial description:
  
  ```
  ## Why Choose Sherpa?
  
  Sherpa stands out as a modern, high-performance solution for end-to-end ASR deployment. It is built upon the `k2` library, which provides highly optimized, GPU-accelerated, and differentiable finite state transducers (FSTs). This foundation enables efficient, modern, and streaming end-to-end speech recognition, making it ideal for production environments requiring speed and accuracy.
