This commit addresses several issues that break device discovery on Windows systems with multiple network interfaces (especially APIPA 169.254.x.x addresses): 1. **send_discovery_frame()**: Wrap socket operations in try/except to handle bind failures gracefully. Windows throws WinError 10049 on APIPA addresses. 2. **send_desc_on_all_if()**: Changed from requiring ALL interfaces to send 3+ messages to requiring ANY working interface. With failing APIPA interfaces, the original logic never returned True. 3. **_stop()**: Removed exception re-raise during shutdown to prevent unhandled exceptions. 4. **_discover_stagelinq_device()**: Return error code instead of raising exception when socket bind fails. This allows discovery to continue on other interfaces. 5. **_py_stagelinq_strapper()**: Fixed to iterate through target_interfaces list instead of calling _discover_stagelinq_device with empty string. 6. Added interface logging in __init__ for easier debugging. Tested on Windows 11 with Denon DJ Prime 4+ and 6 network interfaces (including 2 APIPA addresses).
