Align the document with the [implementation](2841f60686/beacon_node/execution_layer/src/lib.rs (L740)) regarding the `--builder` flag.
The `tokio::join!` macro takes a list of async expressions and evaluates them concurrently on the same task.
## Issue Addressed
Partially #4788
## Proposed Changes
Remove documentation on `/lighthouse/database/reconstruct` API to avoid confusion as the calling the API during historical block download will show an error in the beacon log
Add Events API about `payload_attributes`
## Additional Info
Please provide any additional information. For example, future considerations
or information useful for reviewers.

Some updates in the FAQ based on issues seen on Discord. Additionally, corrected the disk usage on the default SPRP as the previously provided value is not correct.

## Proposed Changes
Correct some typos in the book, also update information about withdrawals since the Mainnet will be having 700K validators in about a month
## Issue Addressed
Update Information in Lighthouse Book
## Proposed Changes
- move Validator Graffiti from Advanced Usage to Validator Management
- update API response and command
- some items that aren't too sure I put it in comment, which can be seen in raw/review format but not live
## Additional Info
Please provide any additional information. For example, future considerations

## Issue Addressed
#4266
## Proposed Changes
- Log `Using external block builder` instead of `Connected to external block builder` on its initialization to resolve the confusion (there's no actual connection there)
## Additional Info
The log is mentioned in builders docs, so it's changed there too.
## Proposed Changes
With proposer boosting implemented (#2822) we have an opportunity to re-org out late blocks.
This PR adds three flags to the BN to control this behaviour:
* `--disable-proposer-reorgs`: turn aggressive re-orging off (it's on by default).
* `--proposer-reorg-threshold N`: attempt to orphan blocks with less than N% of the committee vote. If this parameter isn't set then N defaults to 20% when the feature is enabled.
* `--proposer-reorg-epochs-since-finalization N`: only attempt to re-org late blocks when the number of epochs since finalization is less than or equal to N. The default is 2 epochs, meaning re-orgs will only be attempted when the chain is finalizing optimally.
For safety Lighthouse will only attempt a re-org under very specific conditions:
1. The block being proposed is 1 slot after the canonical head, and the canonical head is 1 slot after its parent. i.e. at slot `n + 1` rather than building on the block from slot `n` we build on the block from slot `n - 1`.
2. The current canonical head received less than N% of the committee vote. N should be set depending on the proposer boost fraction itself, the fraction of the network that is believed to be applying it, and the size of the largest entity that could be hoarding votes.
3. The current canonical head arrived after the attestation deadline from our perspective. This condition was only added to support suppression of forkchoiceUpdated messages, but makes intuitive sense.
4. The block is being proposed in the first 2 seconds of the slot. This gives it time to propagate and receive the proposer boost.

## Proposed Changes
Add some docs on checking the builder configuration, which is a frequently asked question on Discord.
## Additional Info
My text editor also insisted on stripping some trailing newlines, but can put 'em back if we want
## Issue Addressed
Make sure gas limit examples in our docs represent sane values.
Thanks @dankrad for raising this in discord.
## Additional Info
We could also consider logging warnings about whether the gas limits configured are sane. Prysm has an open issue for this: https://github.com/prysmaticlabs/prysm/issues/10810

## Issue Addressed
Related: #3550
Remove references to the `--strict-fee-recipient` flag in docs. The flag will cause missed proposals prior to the merge transition.
Co-authored-by: realbigsean <sean@sigmaprime.io>
## Issue Addressed
Resolves https://github.com/sigp/lighthouse/issues/3517
## Proposed Changes
Adds a `--builder-profit-threshold <wei value>` flag to the BN. If an external payload's value field is less than this value, the local payload will be used. The value of the local payload will not be checked (it can't really be checked until the engine API is updated to support this).

## Issue Addressed
https://github.com/sigp/lighthouse/issues/3091
Extends https://github.com/sigp/lighthouse/pull/3062, adding pre-bellatrix block support on blinded endpoints and allowing the normal proposal flow (local payload construction) on blinded endpoints. This resulted in better fallback logic because the VC will not have to switch endpoints on failure in the BN <> Builder API, the BN can just fallback immediately and without repeating block processing that it shouldn't need to. We can also keep VC fallback from the VC<>BN API's blinded endpoint to full endpoint.
## Proposed Changes
- Pre-bellatrix blocks on blinded endpoints
- Add a new `PayloadCache` to the execution layer
- Better fallback-from-builder logic
## Todos
- [x] Remove VC transition logic
- [x] Add logic to only enable builder flow after Merge transition finalization
- [x] Tests
- [x] Fix metrics
- [x] Rustdocs
