docs: rebrand as Kotlin framework for desktop apps

Update messaging across documentation to position Nucleus as \"the Kotlin framework for native desktop apps\" rather than \"the native desktop platform for the JVM\". This better emphasizes Kotlin as the primary language and aligns with the modern developer experience.

- Update site description and main taglines
- Reorganize navigation to prioritize roadmap over changelog
- Maintain technical accuracy while improving developer appeal

 Not an alternative. An evolution.
 
-Electron gave developers reach but asked them to accept a browser as a runtime, a DOM as a UI layer, and hundreds of megabytes as a baseline. Nucleus builds on the **JVM** and on **Compose Multiplatform** to deliver desktop applications that are natively integrated, natively fast, and natively lightweight.

Nucleus builds on **Kotlin** and **Compose Multiplatform** — running on the battle-tested JVM — to deliver desktop applications that are natively integrated, natively fast, and natively lightweight.
