docs(bf-5klc): verify fix already applied - all tests passing

The vitest mock hoisting errors were already fixed in commit 7686974.
CrossReferencePanel.test.ts and WorkerAnalyticsPanel.test.ts both
use vi.hoisted() correctly and all 2399 tests pass.

+# bf-5klc: Verification - Already Fixed
+
+## Status
+Bead is **closed**. The fix was already applied in commit `7686974fa796ccfd32e7dad2a62f20b665b9f877`.
+
+## Fix Applied
+The vitest mock hoisting errors in both test files were resolved using `vi.hoisted()`:
+
+### CrossReferencePanel.test.ts
+- Used `vi.hoisted()` to declare mock functions (`mockGetEntity`, `mockGetLinksForEntity`, `mockGetStats`, `mockFindPath`)
+- Factory functions now reference these hoisted variables instead of top-level consts
+
+### WorkerAnalyticsPanel.test.ts  
+- Used `vi.hoisted()` to declare `MockWorkerAnalytics` class
+- Mock factory references the hoisted class
+
+## Verification
+All tests pass:
+- CrossReferencePanel.test.ts: 43 tests passing
+- WorkerAnalyticsPanel.test.ts: 64 tests passing
+- Full suite: 2399 tests passing
+
