Add Spatial template library and activate platform (Phase 5)

Completed multi-platform expansion with Spatial Creator Toolkit support,
bringing total platforms to 3 active (Roblox, UEFN, Spatial).

New File: src/lib/templates-spatial.ts
- 10 production-ready Spatial TypeScript templates
- Categories: Beginner (2), Gameplay (4), UI (2), Tools (1), Advanced (1)

Templates include:
1. hello-world - Basic Spatial SDK usage
2. player-tracker - Player join/leave events
3. object-interaction - Click handlers and 3D object interaction
4. countdown-timer - Timer with UI updates
5. score-tracker - Score management with leaderboards
6. trigger-zone - Spatial trigger zones for area detection
7. object-spawner - Spawning objects at intervals
8. teleporter - Teleportation system with pads
9. animation-controller - Advanced object animations
10. voice-zone - Proximity-based voice chat areas

Updated: src/lib/templates.ts
- Import spatialTemplates
- Add to combined templates export
- Total templates now: 43 (25 Roblox + 8 UEFN + 10 Spatial)

Updated: src/lib/platforms.ts
- Changed Spatial status from 'coming-soon' to 'beta'
- Spatial now appears in platform selector
- activePlatforms now includes Spatial

Impact:
✅ 3 platforms now active (Roblox, UEFN, Spatial)
✅ Users can switch to Spatial and see 10 templates
✅ TypeScript syntax highlighting in editor
✅ Translation Roblox ↔ Spatial ready
✅ Translation UEFN ↔ Spatial ready
✅ 43 total templates across all platforms

Strategic Achievement:
- Multi-platform vision expanded
- VR/AR platform support added
- Cross-platform translation covers more pairs
- Competitive advantage strengthened
