feat(docs): Complete Overhaul of README.md for v11+ and AI-Native Focus

This ticket covers a complete refactoring and content update of the main README.md file to align with the v11+ release cycle and the project's new focus on being an AI-native platform.

The previous version was heavily focused on the v10 architecture and did not adequately represent the significant new tooling and concepts introduced in v11.

Key Changes Implemented:

1. Updated Narrative to v11+:

   • Removed outdated references to v10 as the "latest" version.
   • Reframed the v10 architectural blog posts as foundational principles that the current platform is built upon.

2. Prominent AI-Native Section:

   • The "AI-Native" aspect is no longer a minor bullet point. It has been elevated to a primary section right after the introduction.
   • This new section introduces the concept of Context Engineering and briefly explains the three MCP servers (Knowledge Base, Memory Core, GitHub Workflow).

3. Added "A Platform at Scale" Section:

   • To counter the impression of being a "small library," a new section has been added which highlights key metrics about the codebase size (~130,000+ lines of code and documentation).
   • This section provides immediate credibility and communicates the project's maturity and scope. It includes a link to the more detailed CodebaseOverview.md.

4. Consistent "Platform" Terminology:

   • Based on the principles in learn/benefits/Introduction.md, the term "framework" has been replaced with "platform" where appropriate to better describe the holistic nature of the Neo.mjs ecosystem.

5. Content Restoration:

   • Restored code examples for the bind config and the before/afterSet lifecycle hooks that were inadvertently removed in a previous edit.

The updated README.md now provides a more accurate, compelling, and up-to-date overview of the Neo.mjs platform for newcomers and existing community members alike.
