n8n 2.38.4 keeps a working secrets provider alive when its replacement fails to initialize.

Five core fixes with an availability theme (GitHub). #37882 is the one I'd flag: previously, a failed provider init left the instance with no provider at all. #37722 stops Anthropic agent threads breaking permanently and keeps run errors visible instead of swallowed. #37765 caps task runner timeouts to the graceful shutdown window and #37886 stops the task broker before task runner processes on shutdown, two ordering bugs producing hung or half-killed runs.
