* fix(signal): enforce mention gating for group messages
Signal group messages bypassed mention gating, causing the bot to reply
even when requireMention was enabled and the message did not mention
the bot. This aligns Signal with Slack, Discord, Telegram, and iMessage
which all enforce mention gating correctly.
Fixes#13106
