LlamaBarn now uses llama-server in Router Mode. The server stays running in the background and loads models automatically when they are needed. You no longer have to manually select a model before using it. This version also adds an optional "Unload when idle" setting that automatically removes models from memory after a period of inactivity.

• Migrate to llama-server Router Mode
• Introduce "Unload when idle" setting for memory management
• Add automatic download retry logic with exponential backoff
• Add error reporting for failed model downloads
