[symmetric_cipher] [symmetric_cipher] CTR 计数器模式加解密（AES-256-CTR / SM4-CTR）。CTR 是把块密码转成密钥流的模式：加解密为同一操作（密钥流 XOR），无填充，密文长度与明文等长，任意长度输入（1B ~ 16MB）。algorithm 可选 AES256CTR（key 32B，cryptography 实现）或 SM4CTR（key 16B，GmSSL C 库实现，与 eet 的 sm4-ctr 同源）。iv_in_hex 为 16 字节初始计数器块（32 hex 字符），同 key/iv 下加解密互为逆操作。注意：CTR 不提供认证（无 MAC/tag）——需要防篡改时优先用 stream_cipher 的 AEAD 模式（AES-GCM/ChaCha20-Poly1305/SM4-GCM），CTR 仅适合已有独立认证层或互操作对数场景。返回字段：output_data_in_hex、output_length、output_sha256、algorithm。
