/**
 * Kali+ adapter → CustomTool factory (Phase-1).
 * Pins the load-bearing safety + behavior contract:
 *   - catalog_only / import_only adapters are NEVER minted (metasploit/hydra/bloodhound stay off the
 *     callable surface) — the factory returns null.
 *   - a missing binary DEGRADES (returns {success:false, error:<installHint>}) instead of throwing.
 *   - an out-of-scope target is refused (SCOPE DENIED) BEFORE the subprocess runs.
 *   - a mintable adapter produces a CustomTool with a working name + category + real stdout output.
 *   - buildAdapterTools drops non-mintable adapters and skips already-registered tool names.
 * All deps are injected fakes — no real binaries are spawned.
