feat: Add resource search and dungeon room description commands

- Implemented `resource-search` command to allow fuzzy searching of resource labels.
- Added `dungeon-describe-room` command to summarize metadata for a specified dungeon room.
- Enhanced `agent` command handler to support new commands and updated usage documentation.
- Introduced read-only accessors for room metadata in the Room class.
- Updated AI service to recognize and handle new commands for resource searching and room description.
- Improved metrics tracking for user interactions, including command execution and response times.
- Enhanced TUI to display command metrics and session summaries.

-### ✅ Implemented
-- **Simple Chat Mode**: Text-based REPL for automation
-- **GUI Widget Fixes**: Corrected API usage, table rendering
-- **Condensed Documentation**: Streamlined README and ROADMAP
-- **Z3ED_AI Flag**: Simplified build with single master flag
 
 ### 🎯 Next Steps
-1. **Live LLM Testing** (1-2h): Verify function calling works
 2. **GUI Integration** (4-6h): Wire chat widget into main app
 3. **Proposal Integration** (6-8h): Connect chat to ROM modification
 
 ## Troubleshooting
 
-### "AI features not available"
-**Solution**: Rebuild with `-DZ3ED_AI=ON`
-
-### "OpenSSL not found"
-**Impact**: Gemini won't work  
-**Solutions**:
-- Use Ollama (no SSL needed)
-- Install OpenSSL: `brew install openssl`
-
 ### Chat mode freezes
 **Solution**: Use `agent simple-chat` instead of `agent chat`
 
-### Tool not being called
-**Cause**: Model doesn't support function calling  
-**Solution**: Use qwen2.5-coder (Ollama) or Gemini 2.0
