When using seaweedfs/raft (-raftHashicorp=false), also initialize hashicorp raft in parallel. All state changes are written to both raft implementations, keeping hashicorp raft in sync. This enables seamless migration to hashicorp/raft: - No manual steps required for existing deployments - When ready, switch to -raftHashicorp=true and hashicorp raft already has all the state - The old seaweedfs/raft can be removed in a future version Changes: - NewRaftServer now initializes hashicorp raft in a subdirectory - NextVolumeId writes to both raft implementations when both exist - SetRaftServer sets both RaftServer and HashicorpRaft in topology - Transport manager for hashicorp raft is registered for gRPC
