Pull request overview
This PR adds an operator/API mechanism to fast-forward the EVM LogPoller to a new finalized checkpoint (“skip blocks”), including DB-side pruning and the necessary concurrency/atomicity safeguards.
Changes:
- Exposes a relayer-level method to request a LogPoller fast-forward to a target block.
- Adds LogPoller
SkipToBlockplus a new ORM transactional method to prune logs/blocks and store a new finalized checkpoint anchor. - Adds/updates tests and mocks to cover checkpoint storage, transactional behavior, and SkipToBlock edge cases.
