Add Supercomputer category: 12 P2P resource-sharing modules (164 total)

Introduce a new production category for distributed system resource pooling
over Hyperswarm — CPU, RAM, GPU, bandwidth, disk, jobs, cache, and egress.

New modules (supercomputer/):
- hyper-p2p-capacity-registry — gossip CPU/RAM/GPU/disk/bandwidth ads
- hyper-p2p-cpu-share — CPU millisecond credit pool
- hyper-p2p-ram-pool — RAM byte lend/claim/release
- hyper-p2p-gpu-slot — GPU slot register/reserve
- hyper-p2p-bandwidth-share — shared up/down Mbps
- hyper-p2p-disk-stripe — striped block shards
- hyper-p2p-job-dispatcher — submit/claim/complete jobs
- hyper-p2p-thermal-guard — load/temperature throttle signals
- hyper-p2p-cache-farm — distributed LRU cache
- hyper-p2p-net-gateway — peer internet egress routing
- hyper-p2p-cluster-affinity — hardware tag placement scoring
- hyper-p2p-work-stealer — shard queues + work stealing

Each package: index.js, tests, README, api/architecture docs, examples/basic.js.
Shared layering guide: _shared/SUPERCOMPUTER_LAYERS.md.
Registry, module-paths, MODULE_CATEGORIES, and workspace README updated to 164.

Parent workspace also adds docs/supercomputer hub and demo-supercomputer-mesh
(outside this repo).

+# API: hyper-p2p-net-gateway
+
+**Protocol:** `net-gateway/v1` · **Export:** `HyperP2PNetGateway`
+
+## Overview
+
+Peer internet egress gateway registration and routing.
+
+## Constructor
+
+```js
+const mod = new HyperP2PNetGateway(opts)
+```
+
+| Option | Type | Default | Description |
+|--------|------|---------|-------------|
+| `topic` | Buffer \| string \| null | `null` | Hyperswarm topic |
+| `keyPair` | KeyPair | random | Discovery identity |
+
+## Methods
+
+See [`index.js`](../index.js) for the full method list. All modules implement `getStats()`, `async ready()`, and `async close()`.
+
+## getStats()
+
+Returns `{ ...stats, protocol: 'net-gateway/v1' }` plus module-specific counters.
+
+## P2P
+
+When `topic` is set, `ready()` joins Hyperswarm and opens Protomux `net-gateway/v1`.
+
+## Testing
+
+```bash
+npm install && npm test
+```
