/**
 * AI006: Tool / function-calling handler exposed without auth or allowlist.
 *
 * When an LLM can invoke `tools: [...]` and the handler is a Next.js route
 * / Hono endpoint / Express handler with no auth check, a prompt-injected
 * model becomes a confused deputy: it can read the filesystem, call DBs,
 * or send emails on behalf of any user.
 *
 * Detection in AIScanner: looks for `tools:` arrays whose `execute` /
 * handler reaches into `fs`, `child_process`, network fetches, or DB
 * clients without an upstream auth guard.
