/**
 * ContractProvider — small helper that wraps a provider/signer pair and
 * caches the chain ID it's connected to.
 *
 * Used by ByzantineClient and the adapter clients to look up
 * chain-specific addresses without re-querying `eth_chainId` on every call.
 *
 * It does NOT build `ethers.Contract` instances anymore — callers create
 * them directly with `new Contract(addr, abi, provider.runner)`. The
 * thin wrapper is more honest about what it actually does.
