chore: track the parked sync-model handoff

Design input for the last-synced manifest, which is the other half of the propagation fix and still unbuilt. Its point: the locally-edited-and-diverging state isn't rare, because the propagation rule tells projects to patch locally as a stopgap. So an overwrite-and-report has to carry the diff, not just a backup path. A reader needs to tell in one look whether the canonical already contains their patch or whether their change was thrown away and needs re-sending.

working/ is tracked from creation, and this sat untracked while the narrowing shipped around it.
