Fix terminal issues: persistent logs + force HF Spaces rebuild

🔧 Fixes:
1. **Log Preservation**: Replace queue with persistent list + threading.Lock
- Logs now persist throughout session instead of being consumed
- Thread-safe access with proper locking
- Stores last 200 entries, displays last 100

2. **HF Spaces Deployment**: Force fresh rebuild
- HF Spaces was still using old gr.Code version despite gr.Textbox fix
- Small change to trigger complete rebuild and cache refresh
- Should resolve the 'Language bash not supported' error

3. **Improved Log Storage**:
- Uses list instead of queue for persistent storage
- Thread-safe with proper locking mechanism
- Better memory management with rolling window

The terminal will now maintain log history throughout the session
and HF Spaces should properly deploy with gr.Textbox component.
