Flatten the instance `runtime` object into two fields: `runtime` (the JS engine,
node | workerd) and `platform` (the deployment host). The About page shows each
as its own row with friendly labels (e.g. "workerd" + "Cloudflare Workers",
"Node.js" + "Docker").
- Detect the platform from the entry file (entry === target): each serverless
entry declares it; entry-node sniffs Cloud Run (K_SERVICE) / Docker
(ZPAN_RUNTIME, set in the Dockerfile) / bare node. Cloudflare is detected from
the D1 binding.
- Decouple the cloud payload: zpan-cloud-sdk fixes runtime { provider, target },
so CloudInstanceInfo keeps that shape and buildCloudInstanceInfo maps to it;
buildInstanceInfo serves the richer flat shape to the About API.
- Migrate PostHog instance telemetry to the runtime/platform shape and merge the
duplicate runtimeInfo in licensing-admin into the shared one.
