Update docs navigation and homepage links

Updated internal documentation links in the homepage and hero section to reflect new URL structure and improved navigation. Revised the main docs index to focus on the three core ObjectStack protocols, streamlined resource cards, and removed outdated quick links and module descriptions for clarity.

 **ObjectStack** is not just a framework; it is a **Protocol** for building enterprise software. 
 It decouples the *Business Intent* (defined in JSON/YAML) from the *Technical Execution* (handled by the Kernel).
 
 This documentation is the authoritative reference for the ObjectStack Protocol.
 
-## How to navigate
+## The Three Pillars

+ObjectStack is built on three foundational protocols that work together as a unified system:

-## The "Trinity" Architecture
-
-ObjectStack is built on five core modules that work in unison:
+## Why ObjectStack?
 
 | Module | Protocol | Responsibility |
 | :--- | :--- | :--- |
-| **Data Layer** | **[ObjectQL](/docs/specifications/data/architecture)** | Defines the shape of data (`Object`, `Field`) and how to access it (`Query AST`). Agnostic to SQL/NoSQL. |
-| **UI Layer** | **[ObjectUI](/docs/specifications/ui/sdui-protocol)** | The Projection. Defines User Interfaces as abstract JSON layouts (Views, Dashboards, Actions). |
-| **Control Layer** | **[ObjectOS](/docs/specifications/server/kernel-architecture)** | The Kernel. Handles Identity, Security, Sync, and Automation. |
-| **AI Layer** | **AI Protocol** | AI agent definitions, tools, knowledge bases, and model configurations. |
-| **API Layer** | **API Protocol** | Standardized REST/GraphQL contracts with request/response envelopes. |
