Add stream-alarms and acknowledge-alarm to the .NET CLI

stream-alarms attaches to the gateway's central alarm feed (mirrors stream-events: --max-events cap, --json/--jsonl, --filter-prefix); acknowledge-alarm is a unary session-less ack (--reference required, --comment, --operator). Both wired through IMxGatewayCliClient and the adapter. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
