Add Cloud Map seeder discovery with VPC Lattice operator templates.

Agents poll AETHERFORGE_CLOUD_MAP_ENDPOINT to sync know_node gossip; deploy plans attach route_via DNS hints for standalone operator registries.

+# Cloud Map + VPC Lattice (standalone)
+
+Operator templates for **AWS Cloud Map** service discovery and optional **VPC Lattice** service network routing. No live AWS account is required on the AetherForge command deck — host the registry JSON yourself and point agents at it.
+
+## Files
+
+| File | Purpose |
+|------|---------|
+| `registry-endpoint.json` | Cloud Map HTTP registry document served to agents |
+| `lattice-snippet.yaml` | VPC Lattice service network + service association starter |
+| `service-registry.json` | Cloud Map `CreateService` input template |
+
+## Agent configuration
+
+Set on seeders/miners that should poll the registry:
+
+```bash
+export AETHERFORGE_CLOUD_MAP_ENDPOINT="https://YOUR_ORIGIN/registry-endpoint.json"
+```
+
+Agents merge healthy instances into fleet gossip as `know_node` records and refresh LAN seeder hints for WebRTC mesh fallback.
+
+## BGP spread hint
+
+Calibrate `data/config.json`:
+
+```json
+{
+  "server": {
+    "cloud_map_namespace": "prod.local",
+    "cloud_map_service": "seeder"
+  }
+}
+```
+
+Signed deploy plans attach `spread_route_hint.route_via` = `seeder.svc.prod.local` style DNS.
+
+## Operator workflow
+
+1. Export ZIP from Emberwake → **cloud-map** template (or copy files from this folder).
+2. Create Cloud Map namespace `prod.local` and service `seeder` in your AWS account (optional if using HTTP-only registry).
+3. Host `registry-endpoint.json` on S3/CloudFront or Lattice-exposed HTTPS origin.
+4. Apply `lattice-snippet.yaml` when routing VPC workloads through a Lattice service network.
+5. Set `AETHERFORGE_CLOUD_MAP_ENDPOINT` on agents to the hosted registry URL.
+
+## Registry JSON shape
+
+```json
+{
+  "namespace": "prod.local",
+  "service": "seeder",
+  "updated_at": "2026-06-07T12:00:00Z",
+  "instances": [

+      "healthy": true
+    }
+  ]
+}
+```
+
+Healthy instances become `know_node` gossip targets; `fetch_url` feeds LAN seeder hints.
