This PR covers the newly added EVM-only RPC methods in Autobahn's integration test.

Currently, it only exercised six of the EVM-only RPC's methods (eth_sendRawTransaction, eth_getTransactionReceipt, eth_getBalance, eth_getTransactionCount, eth_chainId, eth_blockNumber). Everything added since, from block and receipt lookups to logs, fees, storage, and WebSocket newHeads, was covered only by unit tests against stubbed backends, so nothing checked these methods against a real cluster or that validators agree on what they return.

testEVMOnlyLoad now continues after its 4,000-transfer load.

• assertEVMOnlyBlockQueries takes the block holding a load transfer and checks every block-scoped method against it on all four validators: lookups by number, hash, and index agree with each other and with eth_getTransactionByHash and eth_getTransactionReceipt, the block's receipts sum to its gasUsed, eth_feeHistory reports the same block, and all four nodes return identical blocks and receipts.
• assertEVMOnlyContractQueries deploys a tiny contract whose constructor writes a storage slot and emits a log, then checks eth_getCode, eth_getStorageAt, eth_call, eth_estimateGas, and eth_getLogs against what the constructor did.
• assertEVMOnlyNodeInfo covers net_version, eth_syncing, and the fee suggestions
• assertEVMOnlyNewHeads subscribes to newHeads over each node's WebSocket port and matches the pushed head to the served block. Assertions reuse the existing helpers and per-node client pattern.

The README's method list is rewritten to match what the EVM-only RPC serves, with lists of methods not supported yet and not planned, a short known-limitations section, and fixes to stale lines (the cast wallet new jq path, pruned heights returning an error rather than null, and the removed claim that there are no fee, log, or WebSocket methods).

Test plan

• make autobahn-integration-test passes locally (all four subtests)
• go vet -tags autobahn_integration ./integration_test/autobahn/...
• gofmt, goimports, and golangci-lint fmt --diff clean
• Contract bytecode checked in go-ethereum's EVM before use
• Every README limitation checked against the code

PR Summary

Low Risk
Changes are integration tests and documentation only; no production RPC or node behavior is modified.

Overview
Extends the Autobahn EVM-only integration test so that after the existing 4,000-transfer load it exercises the broader JSON-RPC surface on all four validators, asserting cross-node agreement—not just the six methods covered before.

testEVMOnlyLoad now runs four new assertion phases: block-scoped lookups (eth_getBlock*, receipts, eth_getLogs, eth_feeHistory), node/fee methods (net_version, eth_syncing, eth_gasPrice, eth_maxPriorityFeePerGas), a minimal contract deploy (code, storage, eth_call, eth_estimateGas, logs), and WebSocket eth_subscribe("newHeads"). Shared helpers poll until indexed data is ready and compare JSON across nodes.

The README is updated to document the full supported method set, unsupported vs not-planned methods, and known limitations; it also fixes the cast wallet new jq path, documents pruned-height errors vs null, and states that make autobahn-integration-test validates the documented RPC behavior after load plus one deploy.

Extends the Autobahn EVM-only integration test with block, receipt, log, fee, state, contract and newHeads checks run on all four validators, and rewrites the README method list and limitations to match. I approve: checked against the merge tree (143fb40), the assertions match how the EVM-only RPC behaves (fee-history shape and rounding, the 1 gwei admission floor behind eth_gasPrice, the newHeads cursor, published WebSocket ports, getLogs/feeHistory caps), the hand-assembled contract bytecode decodes as described, and I found no defects. codex reported nothing and I agree; Go is not installed in this sandbox, so nothing was built or run.
