- Double-commit race: null pendingValueRef synchronously at commit() start
so the close-flush + unmount-cleanup guards can't both fire and send a
duplicate PUT for the same value.
- Clamp ceiling: clamp setValue against max(SLIDER_BASE_MAX, currentValue)
instead of Number(raw) (which had no effective upper bound for
programmatic callers).
- Out-of-band staleness: force-revalidate on each activate so a Settings-modal
save (which writes globalMaxConcurrent directly, bypassing this store) is
reflected when a slider surface reopens.
- Load-error label: add an explicit error branch in both EngineControlMenu
and CommandCenterControls so a failed initial load shows "Load failed"
instead of "Ready" while the slider is disabled.
