Add backend-generated sitemap with website manifest sync and nginx SEO proxy support.

Stores synced route config from /meshkee/sitemap-config.json, serves sitemap.xml and robots.txt per tenant, and invalidates cache on CMS writes.

 `kind` is `single` (one image) or `list` (duplicatable). For a fixed row, set `itemCount` (e.g. `2`). Leave `itemCount` null for an unbounded slider. `aspectRatio` must look like `16:9`. Do not invent CMS/upload APIs.
 
+### Sitemap (SEO)
+
+Meshkee generates `https://<WEBSITE_DOMAIN>/sitemap.xml` on the API from published CMS content plus a manifest your site publishes. Nginx on the storefront proxies `/sitemap.xml` and `/robots.txt` to the API — do not hardcode a static sitemap file in the repo unless you know nginx is not proxying yet.
+
+**Publish route manifest** so the business dashboard can sync static pages and URL templates:
+
+`GET https://<WEBSITE_DOMAIN>/meshkee/sitemap-config.json`
+
+```json
+{
+  "baseUrl": "https://sanihome.ir",
+  "staticPages": [
+    { "path": "/", "changefreq": "daily", "priority": 1.0 },
+    { "path": "/about", "priority": 0.6 },
+    { "path": "/contact", "priority": 0.5 },
+    { "path": "/blog", "priority": 0.7 }
+  ],
+  "templates": {
+    "product": "/products/{slug}",
+    "blog": "/blog/{slug}",
+    "portfolio": "/portfolios/{slug}"
+  }
+}
+```
+
+- `path` must start with `/`. Do not include checkout, login, or customer-dashboard URLs.
+- Each `templates` value must include `{slug}` and match how this site routes detail pages.
+- After deploy, the business owner syncs from **Website → Settings** in the dashboard.
+- Dynamic URLs (products, blogs, portfolios) come from the CMS; only paths/templates are declared here.

 If OpenAPI and this brief conflict, **OpenAPI wins**.
