  Reorder README introduction to prioritize core value proposition

  Why:

  CURRENT

  The current README structure places the `[!IMPORTANT]` block immediately after the H1 and initial description, before the detailed explanation of ModelFusion's features.

  COPY-PASTE FIX

  Copy

  Reorder the README's 'Introduction' section to present ModelFusion's core value proposition and features *before* the `[!IMPORTANT]` notice about its integration into the Vercel AI SDK. Ensure the first paragraph clearly states what ModelFusion *is* and *does* as a standalone library, similar to:
  
  ```
  # ModelFusion
  
  > ### The TypeScript library for building AI applications.
  
  ... (badges) ...
  
  ## Introduction
  
  **ModelFusion** is an abstraction layer for integrating AI models into JavaScript and TypeScript applications, unifying the API for common operations such as **text streaming**, **object generation**, and **tool usage**. It provides features to support production environments, including observability hooks, logging, and automatic retries. You can use ModelFusion to build AI applications, chatbots, and agents.
  
  Vendor-neutral**: ModelFusion is a non-commercial open source project that is community-driven. You can use it with any supported provider.
  Multi-modal**: ModelFusion supports a wide range of models including text generation, image generation, vision, text-to-speech, speech-to-text, and embedding models.
  Type inference and validation**: Mode
  
  > [!IMPORTANT]
  > ModelFusion has joined Vercel and is being integrated into the Vercel AI SDK. We are bringing the best parts of modelfusion to the Vercel AI SDK, starting with text generation, structured object generation, and tool calls. Please check out the AI SDK for the latest developments.

  Add a 'Comparison to Alternatives' section in the README

  Why:

  COPY-PASTE FIX

  Copy

  Add a new top-level section to the README titled 'Comparison to Alternatives' or 'Why ModelFusion?'. In this section, explicitly compare ModelFusion to key alternatives like LangChain.js and LlamaIndex.TS, highlighting ModelFusion's unique strengths such as its TypeScript-native design, type safety, and unified API for diverse models.
