fix(ios): bound lifecycle rpcs and claim the target device

a launch the simulator rejects sent the xctest session into a recovery
chain that answered minutes late or never, and the rpc had no deadline,
so the run hung with no trace and no error. also take a per-udid flock:
a second run's reinstall lands under the first's live automation session
and wedges it.
