   ## Summary
   This PR introduces a shutdown-aware bootstrap loop in 
`GlobalStateManagerImpl` and a `consumer.wakeup()` call during 
`GlobalStreamThread.shutdown()` that together let `KafkaStreams#close()` 
interrupt global-store restoration in progress, instead of waiting for the 
entire changelog to be replayed.
   
   ## Implementation
   The global thread passes its `inErrorState()` predicate to the state 
manager, which checks it before each batch in the bootstrap poll loop and exits 
cleanly when shutdown is requested. The `wakeup()` call additionally interrupts 
any in-flight `poll()` so shutdown takes effect right away, even if the loop is 
currently blocked on a fetch. A matching WakeupException catch in the main 
update loop ensures clean shutdowns aren't reported through the 
uncaught-exception handler.
   
   ## Tests
   Added unit tests in `GlobalStateManagerImplTest` covering the supplier check 
and `WakeupException` handling in both `restoreState` and `reprocessState`, and 
end-to-end tests in `GlobalStreamThreadTest` for the close-during-bootstrap 
scenario.
