feat(chain): 添加 init-fullnode.sh — 非创世节点初始化脚本

全节点只需: genexd init + 复制 genesis.json + 配置 peers
区块数据通过 P2P 从创世节点同步，不需要重新执行 genesis 初始化

+# init-fullnode.sh — 初始化非创世全节点 (从创世节点同步)
+#
+# 用法: 由 Docker 容器内执行，需要挂载:
+#   -v <genesis-volume>:/genesis:ro   (创世节点的 .genexd 目录)
+#   -v <node-volume>:/home/genex/.genexd
+#
+# 环境变量:
+#   MONIKER       — 节点名称 (必填)
+#   CHAIN_ID      — 链ID (默认: genex-testnet-1)
+#   PEERS         — 持久对等节点列表 (node_id@host:port)
+# ============================================================
