Pull request overview

This PR centralizes Lighthouse queue name constants in @chimera-monorepo/utils and updates Cartographer backfill to notify Lighthouse when backfill discovers new subgraph data (deduplicating notifications across operations).

Changes:

• Add LIGHTHOUSE_QUEUES to utils constants and re-export it (mqclient now re-exports from utils).
• Update Cartographer core backfill-related operations to return a Set of Lighthouse queues to notify, and update handler backfill to aggregate + notify once per queue.
• Add a handler-level mockable re-export layer and introduce unit tests for backfill notification behavior.

The "deduplicate queue notifications" test currently doesn’t actually exercise deduplication: the stubs return two different queues (INTENT and SETTLEMENT), so the test will pass even if notifications are not deduplicated. Update the stubs so at least two operations return the same queue name and assert notifyLighthouse was called only once for that queue (and align the inline comment with the queues being returned).
