Available on crate feature rpc only.

Converts all TransactionRequests into Recovered transactions and applies them to the given BlockExecutor.

Returns all executed transactions and the result of the execution.

For each call without an explicit gas field, the remaining block gas is used as the default. The RPC gas cap is tracked as a request-wide remaining budget and caps each call before execution. This matches the spec rule "gasLimit: blockGasLimit - soFarUsedGasInBlock" and geth’s per-call sanitizeCall behavior.
