test(unit): add chat and command handler pattern tests
U-002: Chat Handler tests (pattern-based) - Normal message event emission pattern - prevent_default handling - User message alteration pattern - Runner selection pattern - Streaming/non-streaming response patterns - Exception handling modes (show-error, show-hint, hide) - Message history update pattern - Telemetry payload pattern U-003: Command Handler tests (pattern-based) - Command parsing and text extraction - Event creation pattern - Privilege/admin check pattern - Command result handling (text, error, image) - prevent_default handling - String truncation helper Uses pattern-based testing to avoid circular import issues in source code. Direct imports of handler modules trigger circular import chain. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
