feat: forced inclusion (#2797)
ref: #1914 A choice has been made to make this logic in the executor and avoid extending the reaper and the sequencer. This is because, updating the repeer, means passing down the last fetched da height accross all components. It adds a lot of complexity otherwise. Adding it in the sequencer may be preferable, but this makes the inclusion in a sync node less straightforward. This is what is being investigated. Compared to the previous implementation, a forced transaction does not have any structure. It should be the raw structure from the execution client. This is to keep ev-node know nothing about the transaction. No signature checks, no validation of correctness. The execution client must make sure to reject gibberish transactions. - [x] implement for executor - [x] add size checks, to make sure batch doesn't go over max bytes - [x] implement for syncer - requirements: - [x] syncer must be able to detect if sequencer was malicious and hasn't included a forced tx - [x] fetched inclusion of the txs bytes within the block data - [x] if that happened, reject all future sequencer blocks - [x] eventually, become based and keep produce block - [x] tool for submitting forced txs in celestia easily -> evstack/ev-abci#295 - [x] make sure epochs are in sync between syncer and executor ---- for later, won't be included in this pr (ref #2797 (comment)) - [ ] improve offline capabilities (if sequencer goes offline, full node become fully based) - [ ] when sequencer comes back only, needs to fetch if any block was produced :/ --------- Co-authored-by: Marko <marko@baricevic.me>

## [Unreleased]
1111

12+
### Added
13+
14+
- Implement forced inclusion and based sequencing ([#2797](https://github.com/evstack/ev-node/pull/2797))
15+
This changes requires to add a `da_epoch_forced_inclusion` field in `genesis.json` file.
16+
To enable this feature, set the force inclusion namespace in the `evnode.yaml`.
17+
1218
### Changed
1319

1420
- Rename `evm-single` to `evm` and `grpc-single` to `evgrpc` for clarity. [#2839](https://github.com/evstack/ev-node/pull/2839)
1521
- Split cache interface in `CacheManager` and `PendingManager` and create `da` client to easy DA handling. [#2878](https://github.com/evstack/ev-node/pull/2878)
1622
- Improve startup da retrieval height when cache cleared or empty. [#2880](https://github.com/evstack/ev-node/pull/2880)
1723

24+
### Removed
25+
26+
- **BREAKING:** Removed unused and confusing metrics from sequencers and block processing, including sequencer-specific metrics (gas price, blob size, transaction status, pending blocks), channel buffer metrics, overly granular error metrics, block production categorization metrics, and sync lag metrics. Essential metrics for DA submission health, block production, and performance monitoring are retained. [#2904](https://github.com/evstack/ev-node/pull/2904)
