`Eth2NetworkMetadata` has an `incompatible` case to hold an error string
in case the loaded file is not compatible with the compile-time config.
The same can be modeled with a `Result[Eth2NetworkMetadata, string]` and
avoids followup checks for the `incompatible` case.
We use file descriptors for validators and sockets and might run out of
either on high-validator setups - increasing the limit here is harmless
and avoids a common limiting factor in setup

For symmetry with `forkyState` when using `withState`, and to avoid
problems with shadowing of `blck` when using `withBlck` in `template`,
also rename the injected `blck` to `forkyBlck`.

* implement EIP-7514 for Deneb: Add Max Epoch Churn Limit
Cap activations per epoch according to EIP-7514:

- https://github.com/ethereum/consensus-specs/pull/3499
* apply proposer boost to first block in case of equivocation
Implement spec changes to fork choice; this only affects equivocation
when multiple blocks are signed for the same slot. Regular operation
is not changed.

Currently, passing `0xc00000...` proof seems to pass `verifyProofs`.
Unsure why such a check is not necessary in spec, and also unsure
whether it is correct to reject proof at infinity, or if it could
occur, e.g., for a blob containing all 0 bytes. Weird overall...
* proper fix
We currently compute `justified_total_active_balance` inside
`calculateProposerBoost`, despite that sum already being known
in the `EpochRef` cache. Tracking `justified_total_active_balance`
whenever the justified checkpoint updates allows replacing the
repeated computation with a lookup, at minimal memory cost.
The 'vendor/holesky/public-keys/all.txt' file is not used by Nimbus,
but sometimes fails to download due to payment issues in `@eth-clients`.
Skipping the download of that file should reduce that risk.

Currently we always request duties for current and next sync period.
As sync periods are quite long (~27 hrs on Mainnet), having access to
the duties so early doesn't help too much. To avoid running into errors
when the BN does not have the duties available around period boundary,
delay requesting them until the current period is close to finish.
`SYNC_COMMITTEE_SUBNET_COUNT` epochs are what the spec says should be
the lookahead timing of starting to subscribe to sync committee gossip.
Reusing the constant here for consistency.
This fixes these warning messages in the first slot of a new period.

Sync committee duties are performed by the sync committee as determined
by slot + 1. We did it correctly for individual messages, but selected
the incorrect participants for aggregate contributions for the very
first slot per period (roughly 1 per ~27 hrs on Mainnet). The faulty
participants selection code was originally introduced in #2925.
- compact syntax for different options (as in the rest of the guide)
- correct numeration of the list (continuation vs starting from 1)
- add links to useful resources
- a note stating that Prater is deprecated
To allow testing https://github.com/ethereum/consensus-specs/issues/3466
add support for selecting fork choice version at launch. This means we
can deploy a different logic when `DENEB_FORK_EPOCH != FAR_FUTURE_EPOCH`
that won't be used on Mainnet.
