✨ feat(ssr-server): enhance lookup and aggregate handling for SSR cache invalidation

- Improved parsing of `lookup` and `aggregate` options to support JSON strings and arrays.
- Added support for object format in `lookup` and `aggregate` to specify collections.
- Simplified dependency tracking for SSR cache invalidation based on new formats.

+### Automatic dependency tracking via `lookup` and `aggregate`
+
+When options like `lookup` (e.g. `lookup: "image:medialib"`) or `aggregate` (e.g. `aggregate: "comments:contentId:count"`) are provided to an API call, `ssr-server.js` automatically parses these values and adds wildcard cache dependencies (`medialib:*` or `comments:*`) to the page. This guarantees that if a referenced image or child comment changes, the parent's SSR HTML is correctly flushed.

 **Why this works:**
+
 - The `tibi-types` package declares `var context: HookContext` as a global (available because goja provides it during SSR).
 - During SSR, `loadContent()` runs synchronously (goja transforms `async`/`await`).
 - By the time `render(App)` returns in `ssr.ts`, `context.is404` is already `true`.

 **Warum das funktioniert:**
+
 - `loadData()` läuft während der Component-Initialisierung (vor Template-Auswertung)
 - `getCachedEntries` → `apiRequest` → SSR-Pfad → `context.ssrRequest()` → blockierender HTTP-Fetch in goja
 - goja's `await` auf einem bereits aufgelösten Promise läuft synchron weiter (kein Microtask-Hickhack)
