# NeuroSploit v3 - Kali Linux Security Sandbox
# Per-scan container with essential tools pre-installed + on-demand install support.
#
# Build:
#   docker build -f docker/Dockerfile.kali -t neurosploit-kali:latest docker/
#
# Rebuild (no cache):
#   docker build --no-cache -f docker/Dockerfile.kali -t neurosploit-kali:latest docker/
#
# Or via compose:
#   docker compose -f docker/docker-compose.kali.yml build
#
# Design:
#   - Pre-compile Go tools (nuclei, naabu, httpx, subfinder, katana, dnsx, ffuf,
#     gobuster, dalfox, waybackurls, uncover) to avoid 60s+ go install per scan
#   - Pre-install common apt tools (nikto, sqlmap, masscan, whatweb) for instant use
#   - Include Go, Python, pip, git so on-demand tools can be compiled/installed
#   - Full Kali apt repos available for on-demand apt-get install of any security tool
