ARM backends: fix round key byte-swap on little-endian (vrev32q_u8), rewrite decrypt to pre-process middle keys with InvMixColumns, fix GHASH PMULL reflect and reduction ordering. API: add nonce/IV-generating convenience overloads for CTR, CBC, and GCM (library generates and prepends nonce, appends tag). Add C API for IV/nonce generation. Rename error codes (TINYAES_OK, Result::Ok, Result::AuthenticationFailed, etc.). Build: add MinGW GCC AVX-512 debug alignment fix, harden bench/fuzz CMake targets (warnings-as-errors, linker hardening), align with tinysha CMake conventions. Add README. Tests: expand coverage for nonce-generating API overloads, add NIST GCM test vectors, improve fuzz target differential testing.
