fix(roadmap): detect ✓ completion marker in prose slice headers (#1816)

parseProseSliceHeaders() always set done:false regardless of ✓ or
(Complete) markers in the title, causing auto-mode to repeatedly
dispatch complete-slice for already-finished slices.

- Detect ✓ prefix before slice ID ("## ✓ S01: Title")
- Detect ✓ after separator ("## S01: ✓ Title")
- Detect (Complete) suffix ("## S01: Title (Complete)")
- Strip markers from title so downstream consumers get clean names
- Add prose format support to markSliceDoneInRoadmap

Fixes #1803
