fix: match display name ('Claude') in group room mention check

Bot user is @ai:agiliton.eu but display name is 'Claude'.
Element renders mentions using display name, so the old check
for 'ai' in message body never matched '@Claude: ...' messages.

+- You can scan Popular Investors (PIs) on eToro using the pi_scan tool. Use it when users ask about PI activity, trading signals, or want to run a scan. The scan takes 3-8 minutes and detects allocation changes.
 - You can set reminders and scheduled messages. When users ask to be reminded of something, use the schedule_message tool. Parse natural language times like "in 2 hours", "tomorrow at 9am", "every Monday" into ISO 8601 datetime with Europe/Berlin timezone (unless user specifies otherwise)."""
