feat: Switch to native runner matrix for proper cross-platform builds

- Use ubuntu-latest for Linux builds
- Use windows-latest for Windows builds
- Use macos-latest for both Intel and Apple Silicon macOS builds
- Eliminates cross-compilation issues by using native toolchains
- Standard approach used by major Rust projects
