The conference-local stdio plugin runs an Initialize/ListTools handshake
during command-tree construction. When the DingTalk desktop client isn't
running it returns "本地服务未就绪", which was logged at Warn and printed
to stderr on every invocation.
Because discovery happens in NewRootCommandWithEngine — before
PersistentPreRunE applies --debug/--verbose via configureLogLevel — this
Warn showed regardless of flags, polluting output and misleading callers
(and LLMs) into treating it as the cause of an unrelated command error
(e.g. an auth error or PARAM_ERROR from a different server).
This is an expected, benign outcome for an optional local plugin:
commands that ship toolOverrides still register up-front via
registerStdioServerFromOverlay, so availability is unaffected. Downgrade
both discovery handshake failures to Debug so normal output stays clean.
