feat: add pre-built binary distribution infrastructure
- Add GitHub Actions workflow for automated multi-platform releases - Support Linux (x64/ARM64), macOS (Intel/Apple Silicon), and Windows - Add installation scripts for all platforms (install.sh and install.ps1) - Configure Docker multi-arch builds with Alpine for smaller images - Add cross-compilation configuration and build scripts - Update README with binary installation instructions - Optimize release builds for size with LTO and stripping Users can now install DiffScope without Rust using: - curl -sSL .../install.sh | sh (Linux/macOS) - iwr -useb .../install.ps1 | iex (Windows) - Direct binary downloads from GitHub releases 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
