refactor: optimize feature loading in pipeline resume

Reduce redundant file reads by loading the feature object once and passing
it down the call chain instead of reloading it multiple times.

Changes:
- Pass feature object to resumePipelineFeature() instead of featureId
- Pass feature object to resumeFromPipelineStep() instead of featureId
- Remove redundant loadFeature() calls from these methods
- Add FeatureStatusWithPipeline import for type safety

This improves performance by eliminating unnecessary file I/O operations
and makes the data flow clearer.
