ConcurrentDeviceManager::from_manager called bus.enumerate_devices()
a second time inside its constructor — the same buses DeviceManager::
enumerate() had just enumerated to build the remaining list. Renamed
to from_devices(mgr, devices) which takes the already-enumerated
Vec<DeviceInfo> directly, eliminating the redundant I/O and removing
a potential consistency window between the two passes.
