Detailed Description

Progress-event types and callback interface for contour extraction.

The contour machinery can report coarse-grained lifecycle events and fine-grained path-point events through ContourProgressCallback. This is intentionally UI-agnostic: consumers may log events, update a progress bar, or stream contour points as they are produced.
