Review Comment:
Good catch. Removed mutable = true from lineage_event_queue_size. The
LinkedBlockingDeque capacity is fixed at construction time with no
setCapacity() API, so runtime changes via SET GLOBAL would silently have no
effect. Queue size is a low-frequency config — restarting FE to apply changes
is acceptable.
