Pull Request Overview

This PR implements a new ChainOrchestrator to replace the previous indexer, integrates it throughout the node, watcher, network, and engine, and updates tests and database migrations accordingly.

• Introduces ChainOrchestrator in place of Indexer, refactors RollupNodeManager to consume orchestrator events instead of indexer events.
• Adds Synced notifications to L1Watcher and updates engine driver to handle optimistic sync via ChainOrchestrator.
• Refactors configuration (ScrollRollupNodeConfig), network manager, and database migrations; adjusts tests to cover the new orchestrator flows.

• The doc comment uses "blocks" (plural) but the constructor takes a single block; change to "block" for accuracy.

    /// Returns a [`NewBlock`] instance with the provided signature and blocks.

• The follower_can_reorg test has no assertions; either add meaningful checks or remove the empty test to maintain coverage.

async fn follower_can_reorg() -> eyre::Result<()> {

This only skips one Synced notification; consider looping (e.g. while matches!(...) { ... }) to skip all consecutive Synced messages.
