Add 16 tests for main_state_machine.ts branch/function coverage: DiscoveringParams empty queue + persist error, CriticalReads error path, ExecutingCommands GET_PARAMETER_ATTRIBUTES/SCHEDULE_INFORM/REFRESH/SPV callbacks, OperationalState + PartialOperationalState persist errors, error handler + max transitions. Coverage: 93.5% stmts, 73% branches, 77% functions. All 830 tests pass. Build status: Success
