* s3: replicate by fanning out from the gateway to every holder The S3 gateway uploaded each chunk to one volume server, which then relayed the copies to the other replica holders. The gateway now uploads each chunk to every holder in parallel (type=replicate), removing the primary volume server's receive-then-resend relay. AssignVolume returns every replica holder (new repeated Location replicas, forwarded from the master assign), the s3api captures them, and the chunked uploader fans out whenever a chunk has more than one holder. Cipher uploads keep the server-driven path since per-call encryption would diverge the replicas. * s3: cancel sibling replica uploads on the first failure * s3: trim replica fan-out comments * s3: roll back successful fan-out chunk copies when a holder fails A failed fan-out records no FileChunk, so copies that landed on the holders that finished before the cancel were leaked as orphans the caller could not see. Track the holders that succeeded and delete the needle from each (type=replicate, local-only) on failure, leaving nothing behind.
