+ * PR-3: Search Shadow Migration Test
+ * 
+ * Run: node --test test/memory-core/search-shadow.test.mjs
+ * 
+ * Tests the shadow comparison tool:
+ *   1. Shadow tool is runnable
+ *   2. All 22 queries complete
+ *   3. Shape compatibility reported for each
+ *   4. Empty query handled gracefully
+ *   5. Production check still passes
