Rewrite the ss output parser to:
- Skip header lines (State/Netid) explicitly
- Only process LISTEN/UNCONN state lines
- Always read parts[3] for local address (the ss column layout is fixed)
- Defensively skip wildcard (*) port values
The previous fix (PR #235) tried both parts[3] and parts[4], but reading
parts[4] (peer address column) was unnecessary. The ss LISTEN output always
places the local address at index 3 when split by whitespace, for all address
formats: 0.0.0.0:PORT, *:PORT, [::]:PORT, 127.0.0.1:PORT.
