vv0.1.1

Fixed

• Fixed cargo test --no-default-features --lib compilation error
  • SM3 tests: removed alloc dependency, use manual hex parsing
  • SM4 modes tests: added #[cfg(feature = "alloc")]

Changed

• MSRV raised to 1.83.0 (required by crypto-bigint 0.6.x for ConstMontyForm constant-time Montgomery arithmetic)
• Use Rust 1.83+ built-in div_ceil method instead of manual implementation

CI

• Optimized sanity_check.sh to skip test code, avoiding false positives
