Summary

WebUI displays internal metadata blocks (Conversation info, relevant-memories) in the user message input area instead of filtering them

Steps to reproduce

1. Use OpenClaw WebUI in a browser
2. Observe the message input area
3. Internal system metadata blocks (Conversation info, relevant-memories) appear in the user's message input column

Expected behavior

Internal metadata should be filtered out and not displayed in the user's message input area. Only user-authored messages should be visible.

Actual behavior

WebUI displays raw internal metadata blocks including 'Conversation info (untrusted metadata)' and '' content directly in the user message input area. This makes the UI confusing and pollutes the conversation history.
