/**
 * Rename-Create Conflict Test
 *
 * Scenario:
 * - Client 0 creates file A with content "hi" and syncs it
 * - Client 1 syncs (now has A with "hi")
 * - Client 0 disables sync (disconnects WebSocket)
 * - Client 1 renames A to B and syncs
 * - Client 0 (offline, unaware of the rename) creates file B with content "hi"
 * - Client 0 enables sync again
 * - Both clients sync
 *
 * Expected behavior:
 * - The system must resolve the conflict deterministically
 * - Client 0's create of B conflicts with Client 1's rename of A to B
 * - Possible resolutions:
 *   1. One file wins (B contains one version)
 *   2. Files are merged/renamed to avoid collision
 *   3. One operation is rejected
 * - Both clients must converge to a consistent state
