Migrate PERSONAS to flag system for Claude Code compliance

- Add persona flags (--persona-<name>) to flag-inheritance.yml
- Create persona-patterns.yml with behavioral profiles and MCP preferences
- Update command-patterns.yml to reference persona patterns
- Integrate persona flags with MCP decision matrix
- Remove backward compatibility for /persona:<name> syntax
- Update all documentation and examples to use flag syntax

This migration ensures SuperClaude remains compliant with Claude Code's
flag-based architecture while enhancing persona functionality through
standard flag combinations (e.g., --persona-architect --ultrathink).
