Cloud Agent - Filter child session events in event processor

[eshurakov]

Summary

• Filter child/sub-agent session events in event-processor.ts so that onSessionStatusChanged, onStreamingChanged, and the streaming flag are only toggled by root session events.
• Prevents consumers (e.g. Slack bot via run-session.ts) from prematurely disconnecting when a child session emits idle while the parent session is still running.
• Child sessions still get user message completion and onError callbacks — only status/streaming propagation is suppressed.

Changes

event-processor.ts

• Added isChildSession() helper using the existing sessionParents map
• handleSessionStatus: skips onSessionStatusChanged/onStreamingChanged for child sessions
• handleSessionIdle: accepts { sessionID } param; skips streaming toggle for child sessions
• handleSessionError: skips streaming toggle for child sessions; onError still fires for all
• handleSessionTurnClose: passes skipStreamingToggle to forceCompleteAllMessages for child sessions
• forceCompleteAllMessages: accepts optional skipStreamingToggle parameter

event-processor.test.ts

• Added 5 test cases in a child session event filtering describe block covering all filtering scenarios

WARNING

File	Line	Issue
src/lib/cloud-agent-next/processor/event-processor.ts	512	Unsafe cast in session.idle dispatch (data as { sessionID: string }) can pass undefined session IDs at runtime, causing child/root classification and streaming behavior to silently default to root handling. Add runtime validation before calling handleSessionIdle.
