Point the Go client at the StreamAlarms alarm feed

Browse Source 
Regenerate the Go protobuf stubs and replace the session-scoped
QueryActiveAlarms surface with the session-less StreamAlarms feed:
snapshot-then-live AlarmFeedMessage fan-out served by the gateway's
central alarm monitor. Drops session_id from the acknowledge surface.

// QueryActiveAlarms streams a snapshot of all alarms currently Active or
// ActiveAcked — the gateway's ConditionRefresh equivalent. Used after reconnect
// to seed local Part 9 state, or to reconcile alarms that may have been missed
// during a transport blip.
// StreamAlarms attaches to the gateway's central alarm feed. The stream opens
// with one AlarmFeedMessage per currently-active alarm (the ConditionRefresh
// snapshot), then a single snapshot-complete sentinel, then a transition for
// every subsequent raise / acknowledge / clear. It is served by the gateway's
// always-on alarm monitor — no worker session is opened — so any number of
// clients may attach.
//
// The returned stream is owned by the caller; cancel ctx to release it.
// Optional alarm-reference prefix scoping (req.AlarmFilterPrefix) limits the
// stream to a sub-tree.
