* util: match transient error messages case-insensitively, expose the message form The same condition reaches different layers capitalized differently -- a volume server relays its idle timeout as "I/O timeout" inside a JSON string -- and the callers that grew their own substring lists all lower-case first. Also split out IsTransientErrorMessage for the paths that carry only the text, such as the per-file status strings in a batch delete response, and pick up "no route to host" and "network is unreachable" from the gRPC classifier. * filersink: classify transient network errors through util.IsTransientError The local list caught i/o timeout, connection reset, and broken pipe but not connection refused, no such host, unexpected EOF, the syscall errnos, or the gRPC and S3 overload codes. Keep only the bare io.EOF case, which is transient here -- a truncated chunk read -- but a clean stream end elsewhere. * filer deletion: reuse util.IsTransientErrorMessage for the network patterns Six of the sixteen patterns were already covered. Keep the ones specific to this pipeline -- read-only volumes, lookup failures, backpressure -- and note why context cancellation stays retryable here: it decides whether to requeue the deletion, not whether to retry a call. * wdclient: fold the shared classifier into the volume lookup retry check The string tail duplicated the shared list and missed the syscall errnos and net.Error timeouts. Keep "connection" and "timeout", which are broader than the shared classifier on purpose: a volume lookup is a cheap read-only call.
