- New core/aria2_installer.py module downloads the latest aria2c release
from GitHub for Windows, macOS, and Linux with safe path extraction.
- New POST /model_resolver/aria2/install endpoint triggers installation
and saves the resolved aria2c_path plus download_backend=aria2.
- Options UI adds an Install aria2 button, hides aria2-specific fields
when another backend is selected, and updates status on completion.
- Includes .gitignore entry for tools/aria2/ so installed binaries are
not committed.
