## Landing Page Redesign & Demo Subdomain

### Changes
- **New landing page** (`src/app/page.tsx`) — rStack-style dark theme (#0b1120) with gradient hero, 4-card principles, 6-card feature pillars, temporal zoom bar chart, four-view showcase, ecosystem integration cards, and CTA
- **Demo route** (`src/app/demo/`) — Calendar app moved here, served at demo.rcal.online
- **Middleware** — Added `demo` subdomain handling alongside existing space routing
- **Layout restructuring** — Removed global Header from root layout, added per-route layouts for `/calendar`, `/demo`, `/context`
- **Dockerfile fix** — Added `NODE_OPTIONS=--max_old_space_size=4096` to fix SIGSEGV during Docker build
- **Component updates** — AppSwitcher/EcosystemFooter category reorganization (rTube/rSwag to Creating, Social & Media split into Sharing + Observing)
