## Description

<!-- SECTION:DESCRIPTION:BEGIN -->
Create a reusable web component that renders the "Pull rApplet to rSpace" catalog modal.

## Component: `lib/folk-applet-catalog.ts`
- Fetches module list from `GET /:space/modules` API
- Renders cards grid: icon, name, description, enabled toggle, scope badge
- Toggle calls `PATCH /:space/modules` with updated `enabledModules` array
- Accessible from space settings and a "+" button in the app switcher
- Shows sync status indicator (multiplayer/local-only/external)
- Requires space owner authentication to toggle; read-only for members

## Shell integration: `server/shell.ts`
- Add "+" button to app switcher nav that opens the catalog modal
- Only visible to space owners (check `ownerDID` from space meta)

## Files to create/modify:
- `lib/folk-applet-catalog.ts` (new)
- `server/shell.ts` (add catalog trigger button)
- `server/index.ts` (register the new component JS)
<!-- SECTION:DESCRIPTION:END -->

## Acceptance Criteria
<!-- AC:BEGIN -->
- [x] #1 Catalog modal shows all registered modules with icon, name, description
- [x] #2 Space owners can toggle modules on/off with immediate effect
- [x] #3 Non-owners see read-only view of enabled modules
- [x] #4 App switcher updates when modules are toggled
- [x] #5 Works in demo mode with local-only toggle (no API call)
<!-- AC:END -->

## Final Summary

<!-- SECTION:FINAL_SUMMARY:BEGIN -->
Built "Manage rApps" panel into the existing app switcher sidebar. Extends `rstack-app-switcher` with expandable catalog showing all modules (enabled + disabled). Space owners can toggle modules via + / − buttons calling `PATCH /api/spaces/:slug/modules`. Shell passes full module list via `setAllModules()`. Demo mode has local-only fallback.
