refactor: create PipelineStatusInfo interface to eliminate type duplication

Define a dedicated PipelineStatusInfo interface and use it consistently in both
resumePipelineFeature() parameter and detectPipelineStatus() return type.

This eliminates duplicate inline type definitions and improves maintainability
by ensuring both locations always stay in sync. Any future changes to the
pipeline status structure only need to be made in one place.

Changes:
- Add PipelineStatusInfo interface definition
- Replace inline type in resumePipelineFeature() with PipelineStatusInfo
- Replace inline return type in detectPipelineStatus() with PipelineStatusInfo
