test: pin the forced-full route and scope the sync probe to the stage

A stored resolver generation forces a full rebuild, because design stage 5 (incremental optimization) is not implemented. Main's new delta-route assertions now assert FORCED_FULL with a known-gap note saying to restore them; the ADR-survives and incremental-equals-full contracts still run. The #1419 probe counted main's ADR sidecar, which only the full-rebuild route migrates: that sidecar holds user-authored decisions and outlives every publish, so FULL is correct there and the probe now covers the private stage it was written for.
