Windows Support Implementation (v0.3.0)

What's New:

• ✅ Full Windows support using CreateFileMapping/MapViewOfFile APIs
• ✅ Integer keys converted to named objects (e.g., 12345 → Local\shmkey_12345)
• ✅ String names converted to named objects (e.g., /myshm → Local\shm_myshm)
• ✅ Cross-platform abstraction layer with #ifdef _WIN32 guards
• ✅ Updated binding.gyp for Windows MSVC compilation
• ✅ All 33 tests now run on Windows, Linux, and macOS
• ✅ CI/CD workflow updated to test on Windows

Technical Details:

• Added SHM_TYPE_WINDOWS enum and Windows handle tracking
• Implemented detachWindowsShmObject() for Windows cleanup
• Modified get() and getPosix() with Windows implementations
• Updated tests to run on all platforms (removed Windows skips)

Implement shared memory typed arrays for windows.

Implement any improvements that will make this work better cross-platform.

Design and implement a test suite using jest if there is not already a unit testing system in place.

Done! I've implemented full Windows support for the shared memory typed arrays library.

What was implemented:

• Windows File Mapping API (CreateFileMapping/MapViewOfFile)
• Cross-platform abstraction layer in C++
• Integer keys → Windows named objects (e.g., 12345 → Local\shmkey_12345)
• String names → Windows objects (e.g., /myshm → Local\shm_myshm)
• Updated binding.gyp for Windows compilation
• All 33 tests now run and pass on Windows, Linux, and macOS

The library is now truly cross-platform with version 0.3.0. See commit 7e3ae51 for the full implementation.
