Load real GLB models in the MapLibre demo instead of placeholder geometry.

This restores true 3D rendering from backend asset links and keeps runtime var data out of git/agent workflows.

 ## Editing guidance for agents
 
 - Prefer minimal changes and avoid unrelated refactors.
+- Treat `var/` as runtime data only; ignore it for code changes and commits.
 - Add tests when behavior changes.
 - Verify Go tests after backend changes.
 - Verify Bun tests after TS client changes.
 - For DB-required tests, prefer embedded/ephemeral Postgres fixtures over relying on an externally managed database.
 - If CI fails due runner/network infrastructure, keep logs explicit in workflow output.

+## Agent skill memory (current behavior)

+- **Asset downloads stay on backend domain:** `GET /v1/assets/{id}/download` streams bytes from backend (no redirect to MinIO/internal URL).
+- **Asset uploads are backend-routed:** signed upload endpoint returns backend URL (`/v1/assets/{id}/upload`), browser never uploads directly to MinIO.
+- **Public features API exists:** use `GET /v1/features/public` with optional `kind` query (`3d` or `image`) to fetch globally visible features/assets.
+- **Feature geometry update API exists:** `PATCH /v1/features/{id}` updates point geometry (owner only).
+- **MapLibre demo expectations (`web/maplibre-demo.js`):**
+  - uses raster OSM tiles (not vector style),
+  - loads all public 3D features on map start,
+  - after login merges all owner collections,
+  - owner feature markers are draggable and persisted via `PATCH /v1/features/{id}`.
+- **Share-link behavior in demos:** "Copy Share Link" generates map URLs with coordinates so recipients open map context, not only raw asset URL.
