Add sendImages E2E tests for DaemonClient

Add two E2E tests that verify image attachment support in sendMessage():
- "sends message with image attachment to Claude agent" - tests single image
- "sends message with multiple image attachments" - tests multiple images

Tests use minimal 1x1 PNG base64 and verify:
- Server logs image attachments received
- Agent processes message and completes turn
- Assistant response is generated
