Implements alternative to consensus-specs#4992 for addressing ChainSafe#4979's epoch-boundary PTC bug with minimal state changes. Spec: lodekeeper/consensus-specs@feat/minimal-ptc-caching Changes: - Add previousPtc field to gloas BeaconState SSZ type (~4KB, single Vector) - New processPtcUpdate() called at START of process_epoch, before effective balance updates alter the weighted selection - New computePayloadTimelinessCommitteeAtSlot() for on-demand single-slot PTC computation (extracted from epoch-batch computation) - EpochCache: replace previousPayloadTimelinessCommittees (full epoch array) with previousEpochLastSlotPtc (single Uint32Array) - getPayloadTimelinessCommittee() returns cached previousEpochLastSlotPtc for epoch-boundary case, epochCtx cache for current epoch - Initialize previousPtc to zeros in upgradeStateToGloas and genesis - Update specrefs for compute_ptc, get_ptc, process_ptc_update Key design decisions: - No per-slot state rotation (unlike ChainSafe#4992) - Only the last slot of the previous epoch is cached in state because process_payload_attestation enforces data.slot + 1 == state.slot - All epoch PTCs still computed eagerly in epochCtx for duties API - get_ptc_assignment preserved (unlike ChainSafe#4992 which removed it) Co-authored-by: Nico Flaig <nflaig@users.noreply.github.com>

Implements consensus-specs v1.7.0-alpha.4 PTC window changes: - Add ptcWindow field to Gloas BeaconState (Vector[Vector[ValidatorIndex, PTC_SIZE], (2+MIN_SEED_LOOKAHEAD)*SLOTS_PER_EPOCH]) - Add computePtc, computeBalanceWeightedSelection, computeBalanceWeightedAcceptance helpers - Add processPtcWindow epoch processing (runs after processProposerLookahead) - Add initializePtcWindow for fork transition and genesis - Update epochCache.getPayloadTimelinessCommittee to read from state.ptcWindow (read-through) - Remove independently-computed PTC arrays from epochCache - Update compute_balance_weighted_acceptance signature (alpha.4 perf optimization) Spec refs: consensus-specs PRs ChainSafe#4979, ChainSafe#5044

This implements minimal changes to pass `alpha.4` spec tests - adds `ptc_window` to state based on [#4979](ethereum/consensus-specs#4979) - bump spec to `v1.7.0-alpha.4` - update ethspecify - misc changes to pass spec tests **NOTE:** this does not implement any other changes from alpha.4 besides ethereum/consensus-specs#4979 --------- Co-authored-by: NC <17676176+ensi321@users.noreply.github.com>
