v0.1.9 — fix crash on Windows when container Ports is null

Docker Desktop on Windows can return null for c.Ports / c.Labels / c.Names
in the listContainers response (Linux returns empty array/object). The
mapping in discoverServices() assumed array, so .filter() crashed and the
refresh loop kept retrying every 5s, filling the logs.

Closes #7
