Reduce Maru CL engine API parallelism to unblock Besu when behind on sync.

Problem

linea node (besu-pruned-bonsai) on rpc-us-40 stuck syncing. Maru CL 6.6M slots behind tip, thrashing Besu engine API with concurrent newPayload/FCU calls, causing RocksDB stalls. Besu EL head frozen at 31551653 (~4.6 days stale).

Solution

Reduce concurrent engine API calls by tuning Maru config:

  • blocks-parallelism: 10 → 2
  • blocks-batch-size: 10 → 5

This allows Besu to process FCU/newPayload sequentially without saturation, unblocking RocksDB and letting EL head advance while Maru CL catches up.

Verification

  • update.sh regenerated cleanly
  • No hardfork/breaking changes
  • Config tuning only

(vibe-node issue #2412)
