* bump nimbus-build-system to use Nim v2.0.6
* fix: update name and hash for csources of Nim v2
Otherwise we get errors like:
```
Building: Nim compiler
/build/source/vendor/nimbus-build-system/vendor/Nim /build/source
cmd: git clone -q --depth 1 -b master https://github.com/nim-lang/csources_v2.git csources_v2
24.6.0-dirty
cmd: cd csources_v2
ci/funs.sh: line 10: cd: csources_v2: No such file or directory
make[1]: *** [vendor/nimbus-build-system/makefiles/targets.mk:81: build-nim] Error 1
```
Also need to add source for `checksums` repository.

Including sync contributions into a block affects validator rewards.
When we have not received aggregate sync contributions, but have seen
individual messages, we can produce the contributions locally, improving
validator rewards when subscribing to all subnets or when having a
non-aggregating attached validator in the sync committee.
Addresses two inaccuracies in light client data size documentation:
1. `SyncCommittee` pubkeys serialize are 48 bytes not 64 bytes
2. Some of the estimates used 1000 vs 1024 bytes/KB, aligned to 1024
Bellatrix light client data does not contain the EL block hash, so we
had to follow blocks gossip to learn the EL `block_hash` of such blocks.
Now that Bellatrix is obsolete, we can simplify EL syncing logic under
light client scenarios. Bellatrix light client data can still be used
to advance the light client sync itself, but will no longer result in
`engine_forkchoiceUpdated` calls until the sync reaches Capella. This
also frees up some memory as we no longer have to retain blocks.
Using `let contextFork = consensusFork` no longer seems to work to avoid
capturing the `var` loop variable; it ends up being `Electra` for all
handlers. Use `closureScope` as a more sustainable fix.
`ValidatorSig` uses `blob` but `TrustedSig` uses `data`, aligning the
names reduces code duplication and improves clarity. It also simplifies
`StableContainer` compatibility checks.
In nim-web3 all std.Option are replaced by results.Opt. The same goes in nim-eth, with additional fields name changes and GasInt changed from int64 to uint64.
* Beacon node side implementation.
* Validator client side implementation.
* Address review comments and fix the test.
* Only 400 errors could be IndexedErrorMessage, 500 errors are always ErrorMessage.
* Remove VC shutdown functionality.
* Remove magic constants.
* Make arguments more visible and disable default values.
* Address review comments.
