Subject: [PATCH] fix(stream): skip non-object envelopes in
 onResumeStreamReplay

Matches the existing guard in clearResumeFence. A malformed entry
from the server (version skew, serialization mishap) would otherwise
throw on `envelope._replayed = true` mid-iteration and leave the
fence half-flushed via the finally-block.
