Added `-target` flag to swiftc compilation to explicitly specify arm64-apple-macos14.0 or x86_64-apple-macos14.0 based on process architecture, ensuring proper binary compilation for darwin-arm64 native helpers.
Build a standalone C++ helper (same pattern as wgc-capture) that polls
GetCursorInfo() every 50ms and emits STATE:<type> to stdout — identical
protocol to the macOS Swift helper. Windows recordings now capture
correct cursor types (text, pointer, resize, etc.) instead of always
falling back to arrow.
Uses Windows.Graphics.Capture to record the screen without the OS cursor
or the yellow capture border. Falls back to Electron capture on older Windows
or when the helper exe isn't available.
