Base and Reth Ship Fixes for State Root Bug, Users Unaffected

The significance here is less the bug itself than the coordination: a high-priority client release paired with an explicit operator directive shows how much of rollup reliability rests on node operators upgrading promptly. The reassurance that the state root was recomputed and found correct matters because state root divergence is the kind of failure that can silently split a network's view of its own ledger. What's worth watching is whether the upgrade guidance reaches enough of the operator set, and whether similar client-level fixes keep arriving without user-facing disruption.
