fix: subagent unique ID matching + AgentState serialization + pre-existing TS errors

- S-3: Thread task_id (UUID) through all 6 layers (LoopEvent → StreamChatEvent → kernel-types → gateway-client → streamStore) so subtasks are matched by ID, not description string
- AgentState: Add #[serde(rename_all = "lowercase")] to fix PascalCase serialization ("Running" → "running"), update frontend matcher
- S-1: Remove unused onClose prop from ArtifactPanel + ChatArea call site
- Fix hooks/index.ts: remove orphaned useAutomationEvents re-exports (module deleted)
- Fix types/index.ts: remove orphaned automation type/value re-exports (module deleted)
- Fix ChatArea.tsx: framer-motion 12 + React 19 type compat — use createElement + explicit any return type to avoid unknown-in-JSX-child error
