feat: Wire Input Coordinator for Event Tag matching in WR Chat

Implemented event tag detection flow:
- Integrated routeEventTagInput() in handleSendMessage()
- Added generateEventTagMatchFeedback() helper function
- Display match feedback in chat when #tags match agent listeners

When user types '#24 check invoice' and Agent #3 has event trigger '#24':
- NLP Classifier extracts triggers: ['#24']
- InputCoordinator.routeEventTagTrigger() checks all agents' listeners
- Match feedback displayed: 'Match Detected: Agent #3 matched #24'

Supports all Event Tag conditions:
- wrcode_valid: WRCode validation
- sender_whitelist: Sender address check
- body_keywords: Keyword matching
- website_filter: URL pattern matching
