Symphony: execution-aware consensus and proposer disaggregation

Symphony argues that ordinary consensus assumes execution is cheap and deterministic, and that this fails when a transaction is expensive or random. It proposes to split a proposer's control of a block into separate checks, and to accept a proof of delegated work instead of asking every validator to re-run it.
