ci: add GitHub Actions workflow for automated releases

Added a new GitHub Actions workflow to automate the release process when tags matching "v*.*.*" are pushed or triggered manually via workflow dispatch. The workflow performs the following steps:

1. Creates a GitHub Release based on the tag name.
2. Builds release binaries for multiple target architectures (Linux musl x64, Linux musl aarch64, macOS x64, macOS aarch64).
3. Strips binary symbols for Linux builds to reduce size.
4. Generates SHA-256 checksums for each binary.
5. Packages the binaries and checksums into tar.gz files.
6. Uploads the release artifacts (binaries and checksums) to the created GitHub Release.
