SpacetimeDB: subscription-erfaringer, refresh med enrichFromPg, whitespace-fiks

- Dokumentert at subscriptions ikke støtter JOINs (feiler stille)
- refresh() kaller enrichFromPg() for å hente fersk metadata fra PG
- Whitespace-normalisering i autogenererte module_bindings

+## 7. Subscription-begrensninger
+
+**SpacetimeDB-subscriptions støtter IKKE JOINs.** En subscription-query som `SELECT mr.* FROM message_reaction mr JOIN chat_message cm ON cm.id = mr.message_id WHERE ...` feiler stille — `onApplied` kalles aldri, og ingen data vises.
+
+Bruk kun enkle `SELECT * FROM tabell WHERE ...`-queries i `.subscribe([...])`. Filtrer heller klient-side etter at data er lastet.
+
+Eksempel:
+```typescript
+// FEIL — feiler stille, ingen data
+.subscribe([
+  `SELECT * FROM chat_message WHERE channel_id = '${id}'`,
+  `SELECT mr.* FROM message_reaction mr JOIN chat_message cm ON cm.id = mr.message_id WHERE cm.channel_id = '${id}'`
+]);
+
+// RIKTIG — last alle reaksjoner, filtrer i koden
+.subscribe([
+  `SELECT * FROM chat_message WHERE channel_id = '${id}'`,
+  `SELECT * FROM message_reaction`
+]);
+```
+
 ### Fallback
 PG-polling adapter (`pg.svelte.ts`) brukes kun når SpacetimeDB ikke er konfigurert. Markeres som `readonly: true`.
