Root cause analysis: calling create_workstream() before writing the workplan
file creates a ghost workstream with repo_id=null. When fix-consistency later
runs on the file, it creates a second workstream and writes its ID into the
file — leaving the ghost permanently active and showing false partial progress
in the dashboard.
C-14: after checking file-backed workstreams, query active workstreams on the
same topic with repo_id=null. Flag any whose title matches a file-backed
workstream as a probable ghost duplicate.
CLAUDE.md: add explicit "workplan ↔ DB sync rule" prohibiting create_workstream()
for file-backed work. Write file first, then make fix-consistency.
