Prysm Ships 200M Gas Limit Fix Ahead of Glamsterdam Test

This is really a coordination story rather than a client-release story. By hard-coding the new limit as the default, Prysm removes the manual step that previously left operators behind, which matters because a gas-limit change only takes effect if enough validators actually adopt it. The practical effect is that Sepolia's test now reflects operator defaults rather than operator diligence, a meaningful distinction for how future network-parameter changes get rolled out. Whether other clients follow with similar default changes is the open question worth watching.
