Under the hood
Sync clearing reports a distinct repository-left result, and turns whose changes could not ship are marked unshipped.
The directory-sync git worker's clearing logic now returns a distinct repository_left result, carrying setAsideIn, moved, and left details, instead of folding this case into a generic not_cleared/REPOSITORY_LEFT code. Turn records also gain an unshipped flag plus an M.unshippedTurn marker when a turn's changes couldn't be shipped, to support later retry or reporting.
