refactor: Complete SuperClaude v2 migration with @include reference system

- Migrate all command files to use @include reference system
- Consolidate shared patterns into new yml structure
- Create central superclaude shared configuration files
- Remove deprecated markdown files (MCP.md, PERSONAS.md, RULES.md)
- Add new documentation structure in docs/
- Update installation script for new architecture
- Add ROADMAP.md and VERSION files

This completes the major architectural refactor to improve maintainability
and reduce duplication across the SuperClaude command system.
