Fix CLI tests: mock logger to prevent analytics errors, normalize paths

- Mock logger module in image-dimensions.test.ts to prevent analytics
  initialization errors when processImageFile calls logger.debug()
- Mock logger module in local-agents.test.ts for same reason
- Use realpathSync to normalize paths in filePath assertion, handling
  macOS /var symlink to /private/var
