fix(sequencer): submit genesis block to Bedrock on fresh start#409
Conversation
The sequencer created the genesis block's inscribe transaction but discarded it (`_tx`), never posting it to Bedrock. The indexer's `search_for_channel_start` scans backward through L1 blocks looking for an L2 block with `block_id == 1` to locate the channel start. Since genesis was never on L1, the search looped indefinitely, clearing its buffer on every cycle, and `current_state` was never updated past genesis. On a fresh DB start, submit the genesis block to Bedrock immediately after creating it, mirroring what `produce_new_block` does for all subsequent blocks. On restart the genesis block is already on Bedrock from the initial run, so submission is skipped. Fixes the `indexer_state_consistency` integration test.

Hey, thanks for the PR. IMO this is a good addition, but not a fix, because we actually have a thread which retries pending blocks, so it should immediately retry genesis.
Also you can see that indexer tests are still failing. We concluded that this is probably something on bedrock side and currently we disabled this tests in CI while we're waiting for the fix. When you rebase to main you'll see it's removed from CI.
Anyway I'd not merge without @Pravdyvy 's approval.

lgtm. Latest main should fix the tests.
