refactor(scrolls): consolidate protocol files into llm-full.txt

Restructure the scrolls directory by moving all protocol content into llm-full.txt for better maintainability and integration. Remove individual protocol files as they are now fully incorporated into the unified codex. Update references in llm.txt to reflect this change.

The consolidation simplifies the directory structure while preserving all protocol functionality. This change aligns with the antifragility principle of maintaining a single authoritative source that can regenerate the full system if needed.
