Added ARM64 macOS (Apple Silicon) build target support to the CI/CD pipeline by:
1. Including `aarch64-apple-darwin` as a new build variant in the build matrix
2. Adding proper exclusion rules to ensure the target only runs on macOS runners
3. Ensuring compatibility with the existing build scripts and packaging process
This change enables native builds for Apple Silicon Macs, improving performance for users with M1/M2/M3/M4 processors while maintaining the same artifact organization and deployment process.
