New docs site

[debabin]

Create a new documentation prototype based specifically on the shadcn/ui documentation approach and structure. The goal is to follow their documentation style — clean layout, component-driven examples, copy-paste friendly snippets, and practical usage patterns — while adapting it to our own product. The documentation should feel modern, structured, and scalable, similar in clarity and developer experience to shadcn/ui.

Place special emphasis on LLM-related workflows, including concepts such as what can be opened or configured inside an LLM, usage of LLM.txt, and skills. These sections should follow the same practical, example-first philosophy as shadcn/ui docs: clear explanations, real implementation snippets, and real-world scenarios that demonstrate how to integrate and extend LLM capabilities in modern applications.
