[SystemAdmin01]

Summary

• Rework the root README into a technical landing page while preserving HumOS identity and the Cockpit GUI.
• Add an end-to-end Mermaid architecture flow, LINGHOS and G.A.P. explanations, user-facing Cockpit capabilities, quick start, examples, and EN/IT documentation navigation.
• Present the token and performance matrix as indicative design targets, with explicit caveats that measurements are not independently reproduced and downstream LLM inference is not deterministic.
• Align relative links and repository layout with paths verified in the current tree.

Validation

• Confirmed the README update is present on this branch.
• Confirmed one Mermaid block and balanced fenced code-block delimiters.
• Verified the referenced documentation, example, security, contribution, and Cockpit paths against the repository tree.

No application code was changed.
