* ec: strict_placement option so encode only runs while guarantees hold Shard placement during encode was best-effort (PlaceDurabilityFirst): when the cluster could not satisfy the per-disk caps, anti-affinity, replica-placement or per-rack caps, the constraints were relaxed and the volume was encoded anyway, weaker than configured. A strict_placement option on the erasure coding task switches planning to PlaceStrict so the volume's planning fails instead, and the encode is retried when capacity allows the guarantee. Also documents the resilience rule in ec.encode help: a volume survives losing any nodes or racks holding at most parity-shards shards between them, and how -shardReplicaPlacement's rack and node digits bound that loss.
