Implement comprehensive collaborative creative system with cross-character memory sharing

Major Features Added:
• Cross-character memory sharing with trust-based permissions (Basic 30%, Personal 50%, Intimate 70%, Full 90%)
• Complete collaborative creative projects system with MCP integration
• Database persistence for all creative project data with proper migrations
• Trust evolution system based on interaction quality and relationship development
• Memory sharing MCP server with 6 autonomous tools for character decision-making
• Creative projects MCP server with 8 tools for autonomous project management
• Enhanced character integration with all RAG and MCP capabilities
• Demo scripts showcasing memory sharing and creative collaboration workflows

System Integration:
• Main application now initializes memory sharing and creative managers
• Conversation engine upgraded to use EnhancedCharacter objects with full RAG access
• Database models added for creative projects, collaborators, contributions, and invitations
• Complete prompt construction pipeline enriched with RAG insights and trust data
• Characters can now autonomously propose projects, share memories, and collaborate creatively
