"""Verify broadcast — one message to every live session — against a real panel.

1. Two shell sessions, one in a folder; broadcast an echo to all → both run it,
   and the response count is 2.
2. Broadcast scoped to the folder → only that session runs it, count is 1.

Its own home, port and tmux socket; nothing touches a panel you are using.

    python3 tools/broadcast_check.py

Exit status is 0 on pass, 1 on fail.
