zerocopy 0.1.0

Eliminates the Dart↔Native "Copy Tax" using SIMD-aligned C++ shared memory, Pointer.asTypedList() bridging, and an atomic spinlock. Zero serialization. Zero GC impact.

0.1.0

• Initial release.
• Allocates 64-byte SIMD-aligned native memory buffers from C++ via aligned_alloc / posix_memalign / _aligned_malloc.
• Bridges native memory directly to Dart Uint8List via Pointer.asTypedList() — zero data copying.
• Provides an atomic spinlock (std::atomic_flag) for non-blocking thread safety between Dart and native threads.
• Automatic memory management via NativeFinalizer — no leaks even if dispose() is not called.
• Cross-platform native compilation via Dart 3 Native Assets (hook/build.dart) with native_toolchain_c.
• Supports Android, iOS, macOS, Windows, and Linux with no manual build configuration.
• Compiler flags: -O3 -ffast-math -fPIC for maximum native performance.
