- ws.HandlerDeps gains an AlertEngine *alert.Engine field; populated
from http.Deps.AlertEngine (nil until G1 constructs the engine)
- runAgentLoop calls NotifyHostOnline after MarkHostHello succeeds
- dispatchAgentMessage MsgJobFinished case calls NotifyJobFinished,
looking up the job Kind via Store.GetJob before notifying
- store.MarkHostsOfflineStaleReturnIDs added: SELECT+UPDATE in one
transaction, returns the IDs that flipped to offline
- offline sweeper in cmd/server/main.go switched to the new variant;
