I tried eagerly loading replication HarperFast/harper-pro@6fffc73, but that failed (https://github.com/HarperFast/harper-pro/actions/runs/24856733779)
I tried to updated transaction log caching to avoid caching until getRemoteNodeId is available: #400
But that seems rather complicated and weird that we have special logic before a dependency is loaded and there are ids that can't be mapped until it is loaded.
This PR moves the nodeIdMapping.ts module into core, where it is really already pretty heavily used. Which I think is a little more sensible solution.
