Add GitHub Actions release workflow and build scripts

- Add .github/workflows/release.yml for automated releases on version tags
- Add scripts/build-static.sh for building statically linked binaries
- Add scripts/prepare-release.sh for preparing release artifacts
- Optimize Cargo.toml for smaller binary size (reduced from 4.5MB to 2.9MB)
- Add scripts/README.md with usage documentation

The workflow automatically builds binaries for Linux (musl) and macOS (Intel/ARM)
when a version tag is pushed.
