The children filter already skips invalid nodes, so a valid parent
whose only children are invalid becomes a leaf and gets rejected by
node_is_viable_for_head. The top-level check was redundant.
- Add get_filtered_block_tree/filter_block_tree matching the spec's
recursive viability pre-filter for get_head
- Skip invalid execution status nodes in the filter (they aren't in
store.blocks in the spec)
- Fix attestation_score for V17 nodes: fall back to weight() for
Empty/Full since pre-Gloas has no payload separation
- Include head_payload_status in ForkChoiceView so CachedHead updates
when payload status changes
- Update votes test: branch with incompatible finalized leaf is now
correctly excluded by the recursive filter
- Update execution_status test_03: stored weights no longer include
proposer boost
All 30 proto_array/fork_choice tests pass.
All 9 EF fork_choice test suites pass.
The early exit check in recompute_head_at_slot compared only
head_block_root and checkpoints. When on_execution_payload changed
the payload status from Empty to Full without changing the head root,
the CachedHead was not updated. Add head_payload_status to
ForkChoiceView so the change is detected.
Proposer boost is no longer baked into node.weight() — it is applied
on-the-fly in the walk's get_weight via is_supporting_vote. Update
the expected weights in test_03 to reflect pure attestation scores.
- Compute should_apply_proposer_boost once before the walk instead of
per-child per-level
- Clear previous_proposer_boost in apply_score_changes
- Use correct node root in get_ancestor_node error messages
- Add comment explaining is_supporting_vote slot comparison behavior
- Move proposer boost from apply_score_changes to get_weight, matching
the spec's structure where get_weight adds boost via is_supporting_vote
- Implement is_supporting_vote and get_ancestor_node spec functions
- Fix should_extend_payload: return true when proposer_boost_root is zero
- Compute record_block_timeliness from time_into_slot instead of hardcoding false
- Fix anchor block_timeliness to [true, true] per get_forkchoice_store spec
- Add equivocating_attestation_score for is_head_weak monotonicity
- Use payload-aware weight in is_parent_strong
- Add with_status helper on IndexedForkChoiceNode
- Simplify find_head_walk to return IndexedForkChoiceNode directly
Serves envelope by range and by root requests. Added PayloadEnvelopeStreamer so that we dont need to alter upstream code when we introduce blinded payload envelopes.

Closes:
- https://github.com/sigp/lighthouse/issues/8958
- Update the `HotColdStore` to handle storage of cold states.
- Update `BeaconSnapshot` to hold the execution envelope. This is required to make `chain_dump`-related checks sane, and will be generally useful (see: https://github.com/sigp/lighthouse/issues/8956).
- Bug fix in the `BlockReplayer` for the case where the starting state is already `Full` (we should not try to apply another payload). This happens on the cold DB path because we try to replay from the closest cached state (which is often full).
- Update `test_gloas_hot_state_hierarchy` to cover the cold DB migration.

Update spec code for compliance with spec v1.7.0-alpha.3: https://github.com/ethereum/consensus-specs/releases/tag/v1.7.0-alpha.3
The actual consensus changes are minimal. There are few more changes that are only relevant to fork choice or P2P validation that we will pick up in future PRs.
The change "Ignore beacon block if parent payload unknown" is currently covered in a hacky way by `load_parent` and can be improved once we have fork choice.
The change "Add parent_block_root to bid filtering key" is relevant to bid gossip validation, which we don't have at all in unstable yet.

Closes:
- https://github.com/sigp/lighthouse/issues/8869
- Update `BlockReplayer` to support replay of execution payload envelopes.
- Update `HotColdDB` to load payload envelopes and feed them to the `BlockReplayer` for both hot + cold states. However the cold DB code is not fully working yet (see: https://github.com/sigp/lighthouse/issues/8958).
- Add `StatePayloadStatus` to allow callers to specify whether they want a state with a payload applied, or not.
- Fix the state cache to key by `StatePayloadStatus`.
- Lots of fixes to block production and block processing regarding state management.
- Initial test harness support for producing+processing Gloas blocks+envelopes
- A few new tests to cover Gloas DB operations

#7330
Removes `c-kzg` from our `kzg` crate and rely fully on the `rust_eth_kzg` crate.
This removes the old `Blob` type entirely and instead handles `rust_eth_kzg::KzgBlobRef`s directly which allows us to avoid some extra stack allocations . Similarly, we make `Bytes32` and `Bytes48` type aliases rather than structs as this fits better with the new `rust_eth_kzg` API.

We have duplicated features which enable `arbitrary` throughout the codebase. These are `arbitrary` and `arbitrary-fuzz`. I think historically these were supposed to be distinct however in practice these function identically and so we can unify them into a single feature to avoid confusion.

I found myself having to update this code for Gloas, and figured we may as well delete it seeing as it doesn't work.
See:
- https://github.com/sigp/lighthouse/issues/4198
Delete all `fork_revert` logic and the accompanying test.
