Add runnable smoke-test clients for each SDK
Each package gets a small example program that exercises the real
client: with no ORIGIN_SERVICE_KEY set it runs against a local mock
check-in server, otherwise it checks in against ORIGIN_URL/Origin's
public endpoint. Wired into CI (mock mode) as a regression check, and
documented per README.

# @warkanum/origin-client (JS/TS)
```
npm install @warkanum/origin-client
```
Node >=18, ESM only.
## Usage
```ts
import { OriginClient } from "@warkanum/origin-client";
const client = new OriginClient({
serviceKey: "...",
type: "myservice",
version: "1.2.3",
name: "myservice-nova",
});
client.start(); // immediate check-in, then every 24h until stop()
```
Call `client.checkinOnce()` directly instead of `start()` to send a single
check-in and observe the result/error.
## Config
| Field | Required | Default |
|---|---|---|
| `serviceKey` | yes | — |
| `type`, `version`, `name` | yes | — |
| `url` | no | `DEFAULT_URL` (`https://origin.warky.dev/api/public/service-checkin`) |
| `appType` | no | `"javascript"` |
| `hostname` | no | OS hostname |
| `containerId` | no | best-effort Docker/cgroup detection |
| `orchestrator` | no | best-effort Kubernetes/Docker detection |
| `installId` | no | OS machine ID, else a generated UUID persisted to `installIdPath` |
| `intervalHours` | no | `DEFAULT_INTERVAL_HOURS` (24) |
| `logger` | no | discards warnings |
`site`, `environment`, `databaseType`, `databaseName`, `port`, `baseUrl`,
`internalUrl`, `description` are optional metadata with no default.
`hostname()`, `outboundIp()`, `containerId()`, `orchestrator()`, and
`resolveMachineId()` are exported standalone for callers that want the
detection logic without the HTTP client.
## Manual smoke test
```bash
npm run example # single check-in, local mock server
node examples/testclient.mjs --watch # loops via start() until Ctrl-C
```
Set `ORIGIN_SERVICE_KEY` (and optionally `ORIGIN_URL`, `ORIGIN_TYPE`,
`ORIGIN_VERSION`, `ORIGIN_NAME`, `ORIGIN_SITE`, `ORIGIN_ENVIRONMENT`,
`ORIGIN_INTERVAL_HOURS`) to check in against a real endpoint instead.
