Don't track deployment block in the Router

Browse Source 
This technically has a TOCTOU where we sync an Epoch's metadata (signifying we
did sync to that point), then check if the Router was deployed, yet at that
very moment the node resets to genesis. By ensuring the Router is deployed, we
avoid this (and don't need to track the deployment block in-contract).

Also uses a JoinSet to sync the 32 blocks in parallel.
