- Tokio-powered async scanner with configurable concurrency (default: 500) - CIDR subnet expansion (supports /16 to /32) - Uses sectools-common for IP validation and port parsing - clap-based CLI with --target, --ports, --timeout, --concurrency, --output - 8 unit tests for CIDR expansion logic - Updated release workflow to detect Rust tools in tools/ directory - Updated rust.yml, Makefile, README with subnet-scanner
- Add Cargo.toml check to skip non-Go tools in build loop - Narrow Go workflow trigger paths to specific Go tools
