- Introduced a new `loading_fail_sec` parameter in the `wait_backend_idle` function to handle prolonged loading states, improving error handling for backend readiness. - Updated the `ensure_dlbackend_bind` function to stop SwarmUI before remounting, preventing target busy errors and ensuring consistent data mounts. - Enhanced the `recover_errored_backends` function to account for the new remount logic, improving backend recovery processes. - Refactored tests to validate the new loading failure conditions and ensure proper handling of backend states during diagnostics.
