feat(huya): 复刻15/15全量实证 + DiffProbe上线 + C向量更正(ae26d0)

- 8组随机明文×随机钥逐字节命中 → 算法零残差

+Verification: A/B/D/E are the docs/unidbg vectors; C and R* were captured
+live by running the unidbg probe (tools/unidbg/hydev/src/hydev/DiffProbe.java)
+against libudbauthunify_merged.so — 15/15 differential cases bit-exact,
+including 8 fully random plaintext x key pairs.  NOTE: the value stated for
+vector C in the task brief (2cdcf6ad78b8fe0b9ed56004054d2a09) does NOT match
+the real binary; the live output for in="1e8bdf7d4f7a01d3"(16 ASCII), key=B
+is ae26d00a4d5a837baba2903d35135102 (== this replica).
