I noticed that `beacon_node/http_api/src/beacon/execution_payload_envelope.rs` was recently removed but not added to the forbidden-files.txt.
Add the removed file to the forbidden list to ensure it isn't accidentally re-added by a merge or rebase.

The proposer preferences service was attempting to publish preferences at the start of each epoch. This caused it to race with the validator duties service, it wouldn't calculate validator duties in time for the proposer preference service.
This PR first updates the validator duties service to calculate proposer duties for the current epoch and the next epoch. After Fulu we have the ability to look ahead one epoch for proposer duties, but we never updated the vc to leverage this feature.
This PR also updates the proposer preferences service to fire at every slot. We have an `(Epoch, DependentRoot)` map that prevents us from publishing the same preferences twice.
The changes here should prevent the race condition between the two services and make the proposer preferences service more robust in general.

This PR fixes two issues:
1. This condition is inverted: dfb259171a/beacon_node/network/src/network_beacon_processor/gossip_methods.rs (L1507-L1508)
We are supposed to filter out incomplete columns when we DON'T have local blobs yet!
2. When the EL returns no blobs, we never store a partial in the assembler, and this code fails to publish our need to the network, as no partials are returned: dfb259171a/beacon_node/network/src/network_beacon_processor/mod.rs (L1038-L1050)
The simple fix for 1 would be to invert the condition, but we can improve the flow here: Instead of not publishing anything, we can publish what we got, but not request anything. This ties into the fix for 2: After get blobs completes, we not only publish anything in the partial assembler, but also for every missing custody column in there, publish an empty column and a request for all cells.
In particular:
- When sending a partial message to `network`, allow specifying a request bitmap instead of hardcoding an all-ones bitmap.
- For clarity and to prepare for Gloas integration, add a `PubsubPartialMessage` enum with a `DataColumnFulu` variant.
- On republishing after merging a gossip column: always publish, but only request cells if local blobs are known or get blobs is disabled. This also prepares us to request only *some* cells, e.g. in cases where we are aware of the blobs that the EL is going to send us, e.g. via `engine_hasBlobs`.
- Move guards in `fetch_engine_blobs_and_publish` to ensure everything works fine if there are no blobs or if get_blobs is disabled.

Refactors the payload attestation service
- Returns a `Result`. we need this for #9434 so we can keep track if we've succeeded with producing payload attestation earlier than the deadline
- Separates getting payload attestation data and signing + publishing. This mimics what we do in attestation service and also is needed for #9434 to surface the error while still keeping the same spawning mechanism. In #9434 we want to broadcast payload attestations early if we've already seen an avail envelope. If the SSE event fires, but for some reason getting the payload attestation data from the BN fails, we still want to retry at the deadline. If signing + publishing fails we wont retry at the deadline (similar to the attestation service).

Fix a bug in fork choice whereby the unrealized justified and finalized checkpoints from a parent block would be incorrectly carried over to a child block in the same epoch. The documented optimisation in `fork_choice.rs` was wrong because it failed to account for slashings.
This bug is not considered to be sensitive due to the difficulty of triggering it, and the low payoff for doing so (fleeting divergence).
Keep the optimisation, updating it to correctly skip reusing the parent checkpoints when slashings are present.
A more minimal alternative would be to scrap the optimisation altogether (always compute the checkpoints), however this would come with a minor performance downside. I think the updated optimisation is simple enough to be worth retaining.
There are 3 regression tests added which confirm the correct behaviour. Temporarily setting `has_slashings` to `false` causes all 3 tests to fail.

Handle payload-present attestations before the payload is seen (gloas)
A gloas beacon_attestation with index == 1 claims a past block's payload is already present. If we haven't seen that block's payload envelope yet, we shouldn't reject it the envelope may just be in flight.
So instead we IGNORE it (new AttnError::UnknownPayloadEnvelope), ask sync to fetch the envelope, and park the attestation in the reprocess queue. When the envelope is imported, the parked attestations are released and re-verified.
The envelope lookup itself is stubbed here and wired up in #9155 or a follow up PR

Similar to https://github.com/sigp/lighthouse/pull/9476, partial columns is a feature expected to become the default soon, so instead of introducing a CLI option that will be removed again soon, consolidate into `--enable-partial-columns` which now takes a boolean argument.

Single block lookups do not respect the `earliest_available_slot` peers sent. This causes us to potentially request columns from peers that do not custody columns yet (but will soon).
Pass down the block's slot and only consider peers where `earliest_available_slot <= block_slot` for custody column requests.

Use the `LruCache` implementation provided by `hashlink` instead of the current `lru` one.
This is mostly a 1-to-1 swap with only slight API incompatibilities.
I have decided to leave some config files which previously used `NonZeroUsize` but they may not be required anymore and could potentially switch to `usize`.

Bump `discv5` to the latest release. This removes the duplicated `hashlink` dependency and also removes `ahash`.

There's a recent breaking change that deprecated dashboard-based snapshot enablement, and is breaking our CI:
https://www.warpbuild.com/docs/ci/changelog/2026-june#june-8-2026
> Legacy dashboard-based snapshot enablement has been removed. Runners previously configured with snapshots enabled from the dashboard will no longer use snapshots. To continue using snapshot runners, migrate to the label-based configuration by adding snapshot.enabled=true or snapshot.key=<alias> to your runs-on labels. See the [Snapshot Runners docs](https://www.warpbuild.com/docs/ci/features/snapshot-runners) for migration details.

Small collection of improved diagnostics for partials.
- In the peer info struct (exposing peer data via `/lighthouse/peers`), add a new field to indicate on which subnets the peer supports partials.
- Fix the description of several metrics.
- Downgrade some noisy logging when sending partials to trace, and downgrade one warning that should not worry the user.
