Module ctr_streaming 

Streaming SM4-CTR cipher (v0.7 W3).

Stateful counterpart to super::mode_ctr’s single-shot encrypt / decrypt: usable when the plaintext isn’t available all at once (network framing, file streaming, etc).

See super::mode_ctr’s module docstring for the counter contract, the no-authenticity caveat, and the BE counter-encoding semantics — the same rules apply here. CTR is its own inverse, so Sm4CtrCipher serves both directions; there’s no separate Sm4CtrEncryptor / Sm4CtrDecryptor split (compare with CBC’s super::cbc_streaming which needs separate types for the padding-bookkeeping asymmetry).
