/**
 * Regression test for frontier intersection detection bug (Jan 21 2026).
 *
 * BACKGROUND:
 * Commit bec6dbf optimized intersection checking from O(F) to O(1) using
 * nodeToFrontierIndex Map. The bug: Map was updated on every visit instead
 * of only first visit, preventing intersection detection.
 *
 * This test creates a minimal graph where two frontiers MUST meet, verifying
 * that path recording works correctly.
