The HerdR flicker fix routed direct HerdR panes onto the in-place multiplexer resize path, but the randomized render-stress oracle still modeled them as ED3 replaying direct terminals. The width-epoch ledger now applies to any in-place-resize scenario (multiplexer + direct HerdR) via a dedicated resizeRepaintsInPlace trait, keeping HerdR's direct scrollback semantics intact. Adds a deterministic replay regression (seed 0xcafed00d, 24 iterations) that fails without the oracle update.
