fix: gracefully handle Docker/remote Ollama in system-check

When Ollama runs inside Docker or a remote container, the native
'ollama ps' command is unavailable on the host. Instead of hard-failing
and blocking CLI startup, downgrade to a pass() with a warning when
the HTTP ping has already confirmed the server is reachable.
