Adds the session-less alarm CLI subcommands to mxgw-go. stream-alarms attaches
to the gateway's central alarm feed (--filter-prefix, --limit, --json — NDJSON,
one AlarmFeedMessage per line); acknowledge-alarm is a unary ack (--reference
required, --comment, --operator). StreamAlarms joins QueryActiveAlarms on the
public Client and is wired through the existing batch dispatcher via runWithIO.
SDK type aliases for StreamAlarmsRequest / AlarmFeedMessage / StreamAlarmsClient
land alongside the existing alarm types.
