feat(polygon-zkevm): migrate from archived zkevm-node to cdk-erigon
zkevm-node is archived; Polygon mainnet zkEVM operators now run cdk-erigon (an Erigon fork). The prior commit only dropped version tracking — this actually migrates the adapter to the new client: - image -> ghcr.io/0xpolygon/cdk-erigon:v2.64.2, VersionPolicy re-added - config rewritten to cdk-erigon hermez-mainnet yaml (datadir /data, http on 8545 with eth/debug/net/trace/web3/erigon/zkevm apis, externalcl, l2-chain-id 1101, sequencer https://zkevm-rpc.com, datastreamer stream.zkevm-rpc.com:6900, canonical L1 contract addresses) - ContainerArgs: --config=/config/hermezconfig.yaml plus --zkevm.l1-rpc-url=$(L1_RPC_URL); image ENTRYPOINT is cdk-erigon so flags append cleanly. L1 URL still defaults to http://ethereum:8545 via env. - resources bumped to 8 CPU / 16Gi / 2Ti for a mainnet zkEVM node Context: pulled the canonical hermezconfig-mainnet.yaml from the upstream cdk-erigon repo, traced how the operator mounts ConfigTemplate (/config, read-only) and applies ContainerArgs/Env in internal/controller, and confirmed the image entrypoint from its Dockerfile. Build, vet, adapter + controller tests green; versioncheck --chain polygon-zkevm resolves cdk-erigon with no error. Datastreamer/sequencer endpoints are the public Polygon ones — worth a live re-sync check before prod. ~1.5h.
