Summary

WebChat Control UI shows internal system messages (exec completion notifications, session startup messages) directly in the user-visible chat transcript, which should not be exposed to end users.

Steps to reproduce

1. Open WebChat Control UI in browser
2. Run any exec command via the agent (e.g. openclaw plugins list, or any tool that triggers exec)
3. Observe that exec completion/failure notifications appear in the user-visible chat transcript

Expected behavior

Internal exec notifications should not appear in the user-visible chat area. These are gateway implementation details that should be hidden from end users.

Actual behavior

The user sees internal system messages mixed with the conversation. Examples include:

• "System: Exec completed (nova-rid, code 0) :: ..."
• "System (untrusted): Exec failed (wild-sho, signal SIGKILL)"
• Session startup messages injected via /new or /reset (e.g. "A new session was started via /new or /reset...")

These messages are confusing for non-technical users and clutter the conversation.
