/**
 * Stub ImageApprovalAgent - Phase 2 default.
 *
 * Search engine images: returns approve with confidence 0.5 so they auto-approve
 * per FDS §12.4 (LLM auto-approval for search-engine images). Real model is a
 * future swap.
 *
 * Uploaded images: always returns needs_review with confidence 0 so they land
 * in the human moderation queue. Conservative default - no uploads skip review
 * until a real content-screening model is wired.
