EIP-8057: Block Temporal Locality Gas Discounts

Discussion topic for EIP-8057: Block Temporal Locality Gas Discounts

This proposal introduces a deterministic, multi-block discount for the first
access to accounts and storage keys in a transaction. The discount depends on
the number of blocks since that item was last accessed and decays smoothly to
zero over a fixed window of recent blocks. Intra-block warming semantics remain
unchanged (no block-level warming).

The mechanism relies on block-level access lists (EIP-7928) committed in headers so that a newly synced node can price the first block it validates without executing historical blocks.
