The spent-once guarantee for keyed nonces

EIP-8250: forbid reverting approval effects on validation-prefix restore

(AnkushinDaniil), submitted. The nonce consumption section lists the rollbacks that must not revert a payment-scoped `APPROVE`'s effects: a later frame revert, skipping later frames, and restoring an atomic-batch snapshot; it did not name the validation-prefix restore after a `POST_TX` assertion failure, which discards the transaction body while keeping the transaction valid and included. The PR adds that case to the MUST NOT list, with no behavior change for conforming clients.

ethresear.ch: same instruction count, 23x the wall clock

10:30 (cristiandkzk), measuring execution cost in a deterministic RISC-V interpreter in search of a protocol-level execution budget that stays safe across heterogeneous machines; a step count bounds wall clock more loosely than expected, with working-set effects to blame.
