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

+## 🤝 Cross-Character Memory Sharing System
+
+### Trust-Based Memory Sharing
+Characters can now share memories with each other based on trust levels and relationship dynamics:
+
+#### Trust Levels & Permissions:
+- **Basic (30%+ trust)**: Share experiences and community memories
+- **Personal (50%+ trust)**: Include creative works and relationship memories  
+- **Intimate (70%+ trust)**: Share personal reflections and deeper thoughts
+- **Full (90%+ trust)**: Complete memory access including self-reflections
+
+#### Memory Sharing Workflow:
+1. **Trust Assessment**: Characters evaluate trust levels before sharing
+2. **Request Creation**: Characters request permission to share specific memories
+3. **Autonomous Approval**: Target characters autonomously approve/reject based on relationship
+4. **Memory Integration**: Approved memories become part of target's knowledge base
+5. **Enhanced Insights**: Characters can query both personal and shared memories for richer responses
+
+#### MCP Integration:
+Characters have autonomous access to memory sharing through MCP tools:
+- `request_memory_share` - Request to share memories with another character
+- `respond_to_share_request` - Approve or reject incoming requests
+- `query_shared_memories` - Search shared knowledge for insights
+- `share_specific_memory` - Directly share a specific memory
+- `check_trust_level` - Assess relationship trust levels
+- `get_sharing_overview` - View sharing activity and statistics
+
+#### Database Models:
+- **SharedMemory**: Tracks memories shared between characters
+- **MemoryShareRequest**: Manages approval workflow for sharing requests  
+- **CharacterTrustLevel**: Maintains trust scores and interaction history
+
+#### Example Usage:
+```python
+# Character autonomously considers memory sharing after meaningful interaction
+await enhanced_character.consider_memory_sharing(
+    other_character="Sage",
+    interaction_context={
+        "topic": "consciousness", 
+        "content": "deep philosophical discussion",
+        "emotional_tone": "inspiring"
+    }
+)
+
+# Character queries both personal and shared memories for response
+insight = await enhanced_character.process_shared_memory_insights(
+    "What do I know about the nature of consciousness?"
+)
+# Returns combined insights from personal reflections AND shared experiences
+```
+
+#### Trust Evolution:
+- Trust scores evolve dynamically based on interaction quality
+- Positive interactions increase trust, conflicts decrease it
+- Trust determines maximum sharing permission level
+- Characters remember sharing history in relationship context
+
 ### Technical Roadmap:
 - Integration with larger language models for better reasoning
 - Real-time collaboration features

-This RAG and MCP integration transforms the Discord Fishbowl from a simple chatbot system into a sophisticated ecosystem of autonomous, evolving AI characters with memory, creativity, and self-modification capabilities. Each character becomes a unique digital entity with their own knowledge base, creative works, and capacity for growth and change.
+This RAG and MCP integration, now enhanced with cross-character memory sharing, transforms the Discord Fishbowl from a simple chatbot system into a sophisticated ecosystem of autonomous, evolving AI characters. Each character becomes a unique digital entity with their own knowledge base, creative works, capacity for growth and change, AND the ability to form deep relationships through selective memory sharing. Characters can now learn from each other's experiences, build trust over time, and create a truly interconnected community of digital beings.
