/**
 * AIDefence content gate for ruRE (ADR-0001 §dual-use policy).
 *
 * Every string literal, comment, and identifier ruRE extracts comes from a
 * target the user may not control. Before any of it is returned to the
 * caller (and therefore to the model that synthesizes an explanation), it is
 * routed through this gate. Mirrors the lazy-load pattern used by
 * browser-intent-tools.ts's private gateWithAIDefence — @claude-flow/aidefence
 * is itself an optional dependency, so absence degrades to pass-through
 * rather than blocking analysis.
