📌 Description

WST deployments on Sepolia fail with contract creation code storage out of gas at an 8,000,000-gas limit. The reported transaction requires an estimated 22,418,856 gas under Amsterdam state pricing.

Set Ethereum WST deployment gas to 30,000,000 and revise authorization-operation limits using local Amsterdam estimates with at least 30% headroom. Add repeatable measurement tooling that verifies state pricing before reporting results.

🔄 Changes

• Set the Ethereum deployment limit to 30,000,000 gas. Keep the Avalanche deployment limit at 8,000,000 gas.
• Revise the shared Ethereum/Avalanche WST operation limits as shown below.
• Add make measure_wst_gas, backed by two temporary local Anvil nodes. Fork startup works around Anvil v1.8.5's standalone gas-parameter initialization; the source node does not simulate an Osaka-to-Amsterdam upgrade.
• Check EIP-8037 account-creation and new-storage-slot charges before measuring. Stop if the observed prices are too low.
• Add a measurement-only pytest plugin that reports eth_estimateGas, receipt gasUsed, and configured limits. It can raise local transaction limits to complete measurements and exits with status 1 when an estimate or usage exceeds a configured limit.
• Add receive-with-authorization coverage and print deployment usage for a 200-character token name.
• Configure the Ethereum test and measurement nodes with a 60,000,000 block gas limit, matching the observed mainnet block capacity while retaining Amsterdam pricing.
