pub fn from_supercode(home: &Path) -> Result<Workflow>Expand description
Read a supercode home’s boards: each board a ztrack.json marker declares (the default board’s at
kanban/ztrack.json, a named one’s at kanban/boards/<slug>/ztrack.json), from the engine tables the board keeps
beside its document (<marker>.board.db). A home with no such board answers an empty workflow.
