test(multiplayer): detect macOS Godot bundle

 The three declared domain fuzz targets have now each completed a bounded 4-second run (`FuzzQueueCreateDoesNotPanic`, `FuzzResultDigestIsDeterministic`, and `FuzzSyncEventApplicationDoesNotPanic`) with no failures; this closes the locally runnable fuzz portion of 8.46. Live Redis failover, further transaction races, and cloud/runtime gates remain explicitly unverified.
 
 The real ENet integration gate now passes with `GODOT_BIN=/Applications/Godot.app/Contents/MacOS/Godot bash scripts/verify_enet_integration.sh`, covering the `net`, `match-net`, `clock`, `lobby`, and `networked match` process scenarios. The default `GODOT_BIN` remains the portable `godot` PATH lookup for CI; this machine requires the explicit app-bundle path.
+
+The ENet gate now auto-detects `/Applications/Godot.app/Contents/MacOS/Godot` when no PATH executable or `GODOT_BIN` override exists, while retaining explicit override precedence. The same gate passes without an environment override on this macOS host.
