TheOmenDen.StreamPulse.Scripting.Attributes.OnConnectionLostAttributeMarks a method as a handler fired when a monitored socket connection drops abnormally and does not
recover within the debounce grace (spec 023). Never fires for spotify (no socket — strict
matrix). Fires for every other applicable source; read e.Source to branch. The method must
accept (IScriptContext, ConnectionHealthContext). See OnChatMessageAttribute for
the supported return types.
