Driver.Galaxy-002 — DataTypeMap.Map had no Int64 arm though MxValueDecoder/
MxValueEncoder both fully support Int64. Galaxy attributes with the Int64
mx_data_type code fell through to the String default, creating a String
address-space node while runtime reads decoded a boxed long. Added
`6 => DriverDataType.Int64`, extending the contiguous 0..5 scheme so the type
map agrees with the decoder/encoder on all seven Galaxy data types.
Driver.Galaxy-008 — after a stream fault the EventPump's StreamEvents consumer
loop exited and its channel completed; EventPump.Start() is a no-op on a
completed-but-non-null loop, so a replayed subscription had no consumer and
ReplayAsync never re-registered the post-reconnect item handles. ReplayAsync
now recreates the EventPump (RestartEventPumpForReplay) and rebinds the
SubscriptionRegistry per subscription with the fresh item handles returned by
the post-reconnect SubscribeBulkAsync, via new SubscriptionRegistry.SnapshotEntries
and Rebind APIs.
Regression tests: DataTypeMapTests (every code incl. Int64), SubscriptionRegistry
Tests (Rebind/SnapshotEntries), EventPumpStreamFaultTests (faulted pump dead,
fresh pump resumes dispatch).

The ReconnectSupervisor was constructed but its trigger
ReportTransportFailure was never called. When the gateway StreamEvents
stream faulted, EventPump just logged and exited — the supervisor was
never notified, so a transient gateway drop permanently stopped
data-change notifications while GetHealth() still reported Healthy.
EventPump gains an optional onStreamFault callback invoked from its
stream-fault catch block (not on clean shutdown). GalaxyDriver wires it
to ReconnectSupervisor.ReportTransportFailure so a transport drop drives
reopen → replay.
This is the minimal fix for -001; the pump-restart-on-reopen gap remains
tracked as Driver.Galaxy-008. Regression tests cover the callback being
invoked on fault, the end-to-end supervisor reopen/replay, and that a
clean shutdown does not fire it. Driver.Galaxy suite: 206/206 pass.
Resolves code-review finding Driver.Galaxy-001 (Critical).
