Unhead: Universal Head Manager

Unhead is a full-stack, framework-agnostic head manager designed to simplify and standardize how metadata (like `<title>`, `<meta>`, `<link>`) is managed in JavaScript applications. It is currently at version 3.0.4, with frequent patch releases addressing bug fixes and minor improvements, and major versions (like the recent v3.0.0) introducing significant architectural changes, such as the rebuild for streaming SSR. Its key differentiators include comprehensive framework agnosticism, reactive head management, robust server-side rendering support with a focus on streaming capabilities, SEO-friendliness, type safety via TypeScript, and a lightweight, tree-shakable design optimized for performance with minimal runtime overhead. It integrates seamlessly with popular frameworks through dedicated packages like `@unhead/vue` and `@unhead/react`.
