Joseph Doherty 4df8737c86 fix(driver-galaxy): wire event-stream faults to the reconnect supervisor (Driver.Galaxy-001) ...

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).
