Return an error for an unstarted simulator. GetAllControllableDevices creates simulators with deviceKitClient == nil. A direct caller can invoke GetClipboard or SetClipboard before StartAgent, which reaches the nil client and panics. The normal command path starts the agent first, so limit this finding to callers that use discovery results directly. Add a nil-client guard that returns an explicit error, or start the agent and propagate its error before delegation.

In `@devices/simulator.go` around lines 597 - 602, Add a nil-deviceKitClient guard
to SimulatorDevice.GetClipboard and SetClipboard so unstarted simulators return
an explicit error instead of panicking; otherwise start the agent and propagate
any error before delegating to the client.
