Often when testing I have to create a hack which is annoying to maintain.
I think it might be handy to add a custom compile-time flag that developers can use if they want to test things locally without having to backfill a bunch of blocks.
There is probably an argument to have a feature called "backfill" which is enabled by default and can be disabled. I didn't go this route because I think it's counter-intuitive to have a feature that enables a core and necessary behaviour.
## Issue Addressed
The PR fixes a bug where the the ideal rewards for source and head were incorrectly set.
Output from testing a validator that performed optimally in a Phase 0 epoch , note the `source` and `target` under ideal rewards is incorrect (compared to the actual `total_rewards` below):
```json
{
"ideal_rewards": [
...
{
"effective_balance": "32000000000",
"head": "18771",
"target": "18770",
"source": "18729",
"inclusion_delay": "17083",
"inactivity": "0"
}
],
"total_rewards": [
{
"validator_index": "0",
"head": "18729",
"target": "18770",
"source": "18771",
"inclusion_delay": "17083",
"inactivity": "0"
}
]
```
## Proposed Changes
- Fix bad `state_root` reuse in `lcli transition-blocks` that resulted in invalid results at skipped slots.
- Modernise `lcli pretty-ssz` to include fork-generic decoders for `SignedBeaconBlock` and `BeaconState` which respect the `--network`/`--testnet-dir` flag.
## Additional Info
Breaking change: the underscore names like `signed_block_merge` are removed in favour of the fork-generic name `SignedBeaconBlock`, and fork-specific names which match the superstruct variants, e.g. `SignedBeaconBlockMerge`.
## Proposed Changes
Remove patch for `arbitrary` in favour of upstream, now that the `arithmetic_side_effects` lint no longer triggers in derive macro code.

## Proposed Changes
Carries on from #4115, with the following modifications:
1. Self-hosted runners are only enabled if `github.repository == sigp/lighthouse`.
- This allows forks to still have Github-hosted CI.
- This gives us a method to switch back to Github-runners if we have extended downtime on self-hosted.
1. Does not remove any existing dependency builds for Github-hosted runners (e.g., installing the latest Rust).
1. Adds the `WATCH_HOST` environment variable which defines where we expect to find the postgres db in the `watch` tests. This should be set to `host.docker.internal` for the tests to pass on self-hosted runners.

Speed up CI by installing foundry with Github action instead of building Anvil from source.
Building anvil from source on GItHub hosted runners currently takes about 10 mins. Using the `foundry-toolchain` action to install only takes about 2 seconds.

## Proposed Changes
Add lints for rust 1.71
[3789134](3789134ae2) is probably the one that needs most attention as it changes beacon state code. I changed the `is_in_inactivity_leak ` function to return a `ArithError` as not all consumers of that function work well with a `BeaconState::Error`.
## Issue Addressed
This PR attempts to workaround the recent frequent eth1 simulator failures caused by missing eth logs from Anvil.
> FailedToInsertDeposit(NonConsecutive { log_index: 1, expected: 0 })
This usually occurs at the beginning of the tests, and it guarantees a timeout after a few hours if this log shows up, and this is currently causing our CIs to fail quite frequently.
Example failure here: https://github.com/sigp/lighthouse/actions/runs/5525760195/jobs/10079736914
## Proposed Changes
The quick fix applied here adds a timeout to node startup and restarts the node again.
- Add a 60 seconds timeout to beacon node startup in eth1 simulator tests. It takes ~10 seconds on my machine, but could take longer on CI runners.
- Wrap the startup code in a retry function, that allows for 3 retries before returning an error.
## Additional Info
We should probably raise an issue under the Anvil GitHub repo there so this can be further investigated.
## Issue Addressed
Addresses an issue where CI could fail due to an nonexisting file error:
```
Run ./clean.sh
rm: cannot remove '/home/runner/.lighthouse/local-testnet/geth_datadir4/geth/fastcache.tmp.1549331618': No such file or directory
Error: Process completed with exit code 1.
```
This seems to happen quite frequently now, I'm not sure exactly why but perhaps worth trying suppressing the prompt?

## Proposed Changes
Replace `wget` in the EF-tests makefile with `curl`.
On macOS `curl` is pre-installed, and I found myself making this change to avoid installing `wget`.
The `-L` flag is used to follow redirects which is useful if a repo gets renamed, and more similar to `wget`'s default behaviour.
## Issue Addressed
Fixes occasional compilation errors with mev-rs (see #4456).
## Proposed Changes
- Update `mev-rs` to the latest version, which allows us to remove hacky `[patch]` sections
- Update the `axum` version used in `watch` so LH only uses a single version
## Issue Addressed

## Issue Addressed
When trying to run `eth1-sim` locally, the simulator doesn't start for me, and panicked due to duplicate arg names for `proposer-nodes` (using same arg names as `nodes`). Not sure why this isn't failing on CI but failing on mine 🤔
```
thread 'main' panicked at 'Argument short must be unique
thread 'main' panicked at 'Argument long must be unique
```
## Issue Addressed
Fix an issue observed by `@zlan` on Discord where Lighthouse would sometimes return this error when looking up states via the API:
> {"code":500,"message":"UNHANDLED_ERROR: ForkChoiceError(MissingProtoArrayBlock(0xc9cf1495421b6ef3215d82253b388d77321176a1dcef0db0e71a0cd0ffc8cdb7))","stacktraces":[]}
## Proposed Changes
The error stems from a faulty assumption in the HTTP API logic: that any state in the hot database must have its block in fork choice. This isn't true because the state's hot database may update much less frequently than the fork choice store, e.g. if reconstructing states (where freezer migration pauses), or if the freezer migration runs slowly. There could also be a race between loading the hot state and checking fork choice, e.g. even if the finalization migration of DB+fork choice were atomic, the update could happen between the 1st and 2nd calls.
To address this I've changed the HTTP API logic to use the finalized block's execution status as a fallback where it is safe to do so. In the case where a block is non-canonical and prior to finalization (permanently orphaned) we default `execution_optimistic` to `true`.
## Additional Info
I've also added a new CLI flag to reduce the frequency of the finalization migration as this is useful for several purposes:
- Spacing out database writes (less frequent, larger batches)
- Keeping a limited chain history with high availability, e.g. the last month in the hot database.
This new flag made it _substantially_ easier to test this change. It was extracted from `tree-states` (where it's called `--db-migration-period`), which is why this PR also carries the `tree-states` label.
