Unify supercomputer mesh into one virtual machine via cluster-fabric

Add hyper-p2p-cluster-fabric: aggregates every peer's CPU, RAM, GPU, disk,
and bandwidth into a single logical supercomputer (clusterId, asOneMachine).

- getVirtualMachine() — total vs available capacity across all nodes
- publishNode() — join the giant computer; syncs attached pool modules
- reserveCluster() — greedy multi-peer allocation for one workload
- runClusterJob() — reserve + fan-out jobs across slices
- Gossip cluster-node / cluster-reserve / cluster-run on Protomux

Enhance hyper-p2p-capacity-registry with clusterTotals() for the same
aggregate view at the registry layer.

Update SUPERCOMPUTER_LAYERS, category README, demo (3 racks → 44 cores,
155 GB RAM, 5 GPUs as one machine). Registry now 165 modules.
