docs: update README to emphasize MCP-optional design with performance benefits

- Clarify SuperClaude works fully without MCPs
- Add 'Minimal Setup' section (no MCPs required)
- Add 'Recommended Setup' section with performance benefits
- Highlight: 2-3x faster, 30-50% fewer tokens with MCPs
- Reference MCP integration documentation

Aligns with MCP optional design philosophy:
- MCPs enhance performance, not functionality
- Users choose their enhancement level
- Zero barriers to entry
