feat(workspace): setup uv workspace con 2 member (multi-swarm-core + strategy-crypto)

- Root pyproject.toml come workspace coordinator (no codice, dev deps + tool config)
- src/multi_swarm_core/pyproject.toml: package core con dipendenze (pandas, openai, pydantic, ...)
- src/strategy_crypto/pyproject.toml: package strategia con multi-swarm-core come workspace dep
- Aggiunte env var GA_DB_PATH, STRATEGY_CRYPTO_DB_PATH, DASHBOARD_ROOT_PATH in .env.example
- Patch Dockerfile (commento, label, healthcheck per workspace)
- .gitignore: aggiunto .omc/ + state/*.db generico
- Rigenerato uv.lock dal workspace

uv tree mostra:
  strategy-crypto v0.1.0
  ├── multi-swarm-core v0.1.0
  ├── nicegui v3.12.0
  └── ...
