- Adds ethermint query command (`emintcli query ethermint <query>`)
- Supports block number, storage, code, balance lookups
- Implements RPC API methods `eth_blockNumber`, `eth_getStorageAt`, `eth_getBalance`, and `eth_getCode`
- Adds tester utility for RPC calls
- Adheres to go test format, but should not be run with regular suite
- Requires daemon and RPC server to be running
- Excluded from `make test`, available with `make test-rpc`
- Implemented AppModule interface and added EVM module to app
- Required for routing
- Implements `InitGenesis` (`x/evm/genesis.go`) and stubs `ExportGenesis`
- Modifies GenesisAccount to match expected format
