Initial commit — status checker service

Polls Nginx Proxy Manager API for proxy hosts matching configurable
domain patterns (NPM_INCLUDE_PATTERNS), HTTP-checks each every 60s,
serves results as JSON (/api/status) and a terminal-aesthetic HTML
page (/). Port 3035.

NPM connection and domain filter patterns are fully configurable via
environment variables — see README and .env.example.

+# status
+
+A lightweight HTTP status checker that sources its target list from Nginx Proxy Manager and serves results as JSON and a terminal-aesthetic HTML page.
+
+Designed to run as a standalone public status page on its own subdomain — if your main site is down, the status page is still reachable independently.
+
+## How it works
+
+1. On startup (and every 10 minutes), fetches all enabled proxy hosts from the NPM API
+2. Filters to domains matching `NPM_INCLUDE_PATTERNS`
+3. HTTP-checks each host every 60 seconds
+4. Serves current results at `/` (HTML) and `/api/status` (JSON)
+
+The HTML page auto-refreshes every 60 seconds.
+
+## Running locally
+
+```bash
+cp .env.example .env
+# fill in NPM_EMAIL and NPM_SECRET
+npm install
+npm run dev
+```
+
+## Environment variables
+
+| Variable | Default | Description |
+|---|---|---|
+| `PORT` | `3035` | Port to listen on |
+| `NPM_BASE_URL` | `http://localhost:81` | Base URL of your Nginx Proxy Manager instance |
+| `NPM_EMAIL` | — | NPM account email |
+| `NPM_SECRET` | — | NPM account password |
+| `NPM_INCLUDE_PATTERNS` | `\.example\.com$` | Comma-separated regex patterns; only domains matching at least one are checked |
+
+## Docker
+
+```bash
+docker compose up -d
+```
+
+Uses the image from `IMAGE` in `.env`. For a local build:
+
+```bash
+docker build -t status:local .
+IMAGE=status:local docker compose up -d
+```
+
+## CI/CD
+
+Gitea Actions workflow at `.gitea/workflows/build.yml`. Builds and pushes to the Gitea container registry on every push to `main`. Requires a `TKNTKN` secret (PAT with `packages:write`) in the repo settings.
+
+## API
+
+```
+GET /api/status
+```
+
+```json
+{
+  "lastRefreshed": "2026-07-07T19:35:43Z",
+  "hosts": [
+    {
+      "name": "example.com",
+      "url": "https://example.com",
+      "status": "up",
+      "statusCode": 200,
+      "latencyMs": 182,
+      "checkedAt": "2026-07-07T19:35:43Z"
+    }
+  ]
+}
+```
+
+`status` is `"up"` for any response (including 4xx — the server is reachable), `"down"` for connection errors and 5xx, `"unknown"` before the first check completes.
