fix: address code review findings from CodeRabbit

- Remove duplicate idle-state tests in GenerateImageNode and GenerateVideoNode
- Fix misleading "Text target labels" comment to "Text source labels"
- Use object-contain on AnnotationNode so full image is visible for annotation
- Add abort signal checks to Router/Switch/ConditionalSwitch executors
