Pull Request Overview

This PR overhauls the README to improve clarity, navigation, and completeness by reorganizing the header, adding new sections, and fixing links.

• Introduce a centered title banner with updated badges and quick links.
• Add “Key Features,” expanded installation options (Yarn, Pnpm, Bun), usage examples, and detailed TypeScript definitions.
• Reformat the OpenAPI support details into a rules table and expand sections on contributing, contributors, star history, credits, and license.
