Resolve Client.Java-032..036: shared subscription base, batch tokenizer

Browse Source 
Client.Java-032  README CLI examples for stream-alarms and
                 acknowledge-alarm now use the correct picocli flags
                 (--filter-prefix and --reference); two regression
                 tests parse each documented invocation.
Client.Java-033  StreamAlarmsCommand publishes an
                 AtomicReference<MxGatewayAlarmFeedSubscription> and
                 mirrors MxEventStream's overflow branch: a failed
                 queue.offer cancels the subscription, queues an
                 IllegalStateException, then queues the END sentinel
                 — preserving the fail-fast contract.
Client.Java-034  BatchCommand routes through a new
                 MxGatewayCli.tokenizeBatchLine POSIX-style shell
                 tokenizer that respects double-quoted, single-quoted,
                 and backslash-escaped arguments.
Client.Java-035  Added streamAlarmsForwardsRequestAndStreamsAlarmFeedMessages
                 to MxGatewayClientSessionTests; asserts request shape,
                 message ordering, and cancellation propagation.
Client.Java-036  Extracted MxGatewayStreamSubscription<TRequest,TResponse>
                 abstract base; the four subscription classes
                 (MxGatewayEventSubscription, MxGatewayAlarmFeedSubscription,
                 MxGatewayActiveAlarmsSubscription, DeployEventSubscription)
                 collapse to ~10-line subclasses. A new contract test
                 runs identical lifecycle / cancellation assertions
                 across all four subclasses.

All resolved at 2026-05-24; gradle build + gradle test BUILD SUCCESSFUL.
