Regression (worked before, now fails)

Summary

When two TUI windows are connected to the same agent, creating a new session with /new in one window causes the agent's replies to be broadcast to all connected TUI clients, not just the one that initiated the session.

Steps to reproduce

1. Open terminal window A and connect to an agent via TUI: openclaw tui, then /agent main
2. Open terminal window B and connect to the same agent: openclaw tui, then /agent main
3. In window A, type /new to create a new session.
4. Send a message in window A, e.g., "Hello".
5. Observe: the agent's reply appears in both window A and window B.

Expected behavior

Each TUI client should maintain its own session context. Messages and replies in a session created by /new in window A should not appear in window B. Session-level isolation should be enforced.

Actual behavior

The agent's reply is broadcast to all connected TUI clients regardless of which client initiated the session.
