Subject: [PATCH] fix: use binary search for eth gas estimate (#296)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

- Build the node with Frontier’s rpc-binary-search-estimate feature so
eth_estimateGas runs the same iterative search as Moonbeam.
- Instead of returning the gas spent by a single max-allowance dry run,
the RPC now repeatedly replays the transaction while shrinking the gas
cap until it finds the smallest limit that still succeeds.
