Fixes openclaw#47188
Problem
After upgrading to 2026.3.13, streaming responses in webchat create multiple duplicate message bubbles with growing text, instead of updating a single message in-place.
Root Cause
Each segment stored the full cumulative text rather than the delta, causing multiple overlapping bubbles.
Fix
Each segment now stores only the delta (new text since last segment), preventing visual duplication while preserving the correct text→tool→text rendering order.
Note: Resubmission of openclaw#47344 which was auto-closed due to PR queue limit.
