Till JS bd1178edf8 feat(traces): integrate traces app into monorepo with NestJS backend and AI city guides
Restructure standalone traces app into monorepo pattern with mobile + backend + shared types.
Add NestJS backend with Drizzle ORM schema for locations, cities, places, POIs, and AI guides.
Add mobile sync layer, cities tab, and guide generation UI. Fix pre-existing type errors across
mobile codebase, matrix-mana-bot (sendDirectMessage), llm-playground, and all web auth stores
(signUp call signature).

# CLAUDE.md - Traces
GPS tracking app with AI city guides. Location tracking runs locally via AsyncStorage, with optional backend sync.

## Commands
```bash
# Development
pnpm dev:traces:mobile # Start Expo app
pnpm dev:traces:backend # Start NestJS backend
pnpm dev:traces:full # Start auth + backend + mobile
# Database
pnpm traces:db:push # Push Drizzle schema
pnpm traces:db:studio # Open Drizzle Studio
```
## Architecture
- **Mobile**: Offline-first. All GPS data in AsyncStorage. Sync is additive.
- **Backend**: NestJS + Drizzle ORM + PostgreSQL. Auth via ManaCoreModule.
- **AI Guides**: Uses mana-search for POI discovery, mana-llm for narratives.
- **Credits**: 5 base + 2 per POI consumed via CreditClientService.
