MrEchoFi/BannerGrapV2 ? reverse-engineered prompt

Build me a fast command line network recon and vulnerability discovery tool in Go, like the BannerGrapV2 project. It should scan one host or many hosts, grab service banners, fingerprint common services, check SSL and TLS certificates, pull HTTP headers, do basic DNS lookup, and flag likely weak credentials or common misconfigurations when possible. I want it to run concurrently so it can handle large target lists without feeling slow, and it should support timeouts, rate limiting, and resuming failed scans.

Please make the output useful for real security work, with clean terminal results plus JSON, CSV, XML, and HTML reports. It should work on Linux, macOS, and Windows, and be easy to build from source or run with Docker. If it makes sense, add a simple way to integrate Nmap style checks and maybe a Kubernetes or container friendly setup. Keep it practical, polished, and easy to use from the terminal, and look up current Go docs online if you need to.
