Redesign README with modern layout and add Chinese version

- Restructure README.md with centered logo, badges, and feature tables
- Add usage examples for DuckDB analytics and vector search
- Add visual roadmap and star history chart
- Create README_zh.md for Chinese-speaking users
- Remove emoji icons for cleaner appearance

-## Features
+---
 
-- **[DuckDB Storage Engine](./wiki/duckdb/duckdb-en.md)**:AliSQL integrates DuckDB as a native storage engine, allowing users to operate DuckDB with the same experience as MySQL. By leveraging AliSQL for rapid deployment of DuckDB service nodes, users can easily achieve lightweight analytical capabilities.
+## Why AliSQL?
 
-- **[Vector Storage](./wiki/vidx/vidx_readme.md)**:AliSQL natively supports enterprise-grade vector processing for up to 16,383 dimensions. By integrating a highly optimized HNSW algorithm for high-performance Approximate Nearest Neighbor (ANN) search, AliSQL empowers users to build AI-driven applications—such as semantic search and recommendation systems—seamlessly using standard SQL interfaces.
+AliSQL brings enterprise-grade capabilities to MySQL, combining the reliability of InnoDB OLTP with DuckDB's blazing-fast analytics and native vector search — all through familiar MySQL interfaces.
